How to Build Muscle Fast (Training, Diet, and Workouts)

Want to build muscle like this guy?

(Leopard print unitard optional but encouraged)

In this guide, we’ll provide step-by-step instructions that will help you start building muscle immediately. Like, today.

We’ll explore:

That may seem like a lot of topics to cover. DON’T PANIC!

If you want to build muscle, get bigger, and become stronger, it comes down to three things done consistently:

Lift heavy things
Eat enough calories and protein for your goals
Get enough rest

I realize doing those three things is much easier said than done. Doing hard stuff consistently for months and years requires a great strategy!

In fact, we even helped our friend on exactly how important these three things are.

If you want some help implementing these strategies in your own life, weprovide a free bodyweight routine, and a comprehensive gym training routine to get you started with strength training in our free guide, Strength Training 101: Everything You Need to Know.

How Do You Build Muscle and Strength?

If you are going to build strength and muscle, you need to lift heavy things to force your muscles to rebuild themselves stronger.

But what the heck does ‘heavy’ mean in this context? I’m so glad you asked!

Muscle-building is optimized when performing strength-training exercises in the 5 to 30 rep range (bodyweight or weightlifting), working to within 1 to 3 reps of failure while maintaining good technique.

(i.e. You could do 1 or 2 or 3 more repetitions of the exercise using a specific weight, but not more.) Usually, you’ll repeat this effort for multiple sets targeting multiple muscles in a workout.

That’s what I mean by ‘lift heavy’: you picked the right amount of weight to challenge yourself for the desired number of reps. By forcing your muscles to really tax themselves by picking up heavy things, you are participating in the Holy Grail of muscle building: progressive overload!

Progressive overload: forcing your muscles to rebuild themselves stronger by increasing the challenge they face with each workout. Examples include: lifting heavier weight, doing more reps, frequency, etc.

For example, from one week to the next, progressive overload would look like:

Week 1 Barbell Squat: 4 sets of 6 reps at 150 lbs.
Week 2 Barbell Squat: 4 sets of 6 reps at 155 lbs.

If you do that, you’ve gotten stronger! Then, repeat next week. Consume enough calories and protein, and you’ll gain muscle mass too.

“Got it, Steve. I need to pick up heavy things. Can we talk about which exercises I should do to build muscle?”

Great question, you good-looking person. I’ll cover specific exercises in the following section, but let’s start with a broader point:

Free weights, machines, and exercises are ALL good options as long as you can adhere to the guidelines we laid out above.

While you can grow muscle using any type of strength-training exercise, having access to a makes leveling up your muscle-building game all the easier.

Check out our for everything you need to know and getting started in a gym with sample workouts.

So let’s start building muscle!

We’ll want a routine with that train multiple muscle groups at once. They’re efficient and they can create solid growth and stimulation.

To create our full-body routine, each workout will make sure it has a big compound leg exercise, push exercise, and pull exercise:

Leg Exercises (Quad Dominant or Hip Dominant): , , or
Push Exercises:, , or
Pull Exercises:, or

Learn these few exercises, get really good at them, and your entire body will get stronger and bigger. Focus each week on adding more weight to each exercise.

Bottom line: if you want to get bigger muscles, you need to challenge them regularly with exercises that bring the muscle close to failure (1 to 3 reps). To start, we recommend picking big, compound movements that work multiple muscles at a time.

“Steve, what about isolation exercises like bicep curls, tricep extensions, calf raises, etc.?”

Absolutely add these in whenever you want to, though we recommend starting with the workout we laid out above FIRST and getting consistent with that. Muscle-building isn’t just about picking the right exercises and the right weights, it’s about building the habit of working out!

If you try to do ALL THE THINGS at the very beginning, you’re increasing the risk that you won’t be able to .

Start with compound exercises that give you the biggest bang for your buck, THEN sprinkle in isolation exercises that target your specific areas of need.

“What about machines versus free weights? I’ve heard free weights are better…”
Not true! If a machine exercise feels safer, is more easily accessible to you, and targets the same muscles – go for it. The important thing is that you are challenging your muscles to get stronger, that’s it.

What’s a Sample Routine for Building Muscle?

Using the principles I’ve laid out in my “” article, here’s a beginner three-day routine:

Monday:, ,
Wednesday:, ,
Friday:, ,

Each day has a leg exercise, push exercise, and a pull exercise.

Besides having rest and recovery days in between MWF, adequate rest intervals have been established in the workout itself!

By following the leg exercise, push exercise, and a pull exercise routine you will maximize rest in-between each exercise, therefore, limiting muscular fatigue and allowing you to perform each strength training exercise to its fullest extent.

Now, this is just a basic, 3-day, Full-Body workout routine. We have a whole guide on how to , but there are infinite ways to build a strength training routine.

4-Day Push-Pull split:

Monday: Push exercises
Wednesday: Pull exercises
Friday: Push exercises
Saturday: Pull exercises

4-Day Upper Lower Split:

Monday: Lower Body
Wednesday: Upper Body
Friday: Lower Body
Saturday: Upper Body

Bodybuilders often prefer to follow a 5-day “each day gets one body part” workout. While this is a popular split, we recommend hitting each muscle group 2x/week for more efficient gains.

Monday: Legs (quad dominant)
Tuesday: Chest
Wednesday: Back
Thursday: Legs (hip dominant)
Friday: Arms

Yes, there’s even a 6-day split!(We muscle-building nerds can come up with endless ways of organizing our training.

Monday: Legs
Tuesday: Upper Body Push
Wenesday: Upper Body Pull
Thursday: Legs
Friday: Upper Body Push
Saturday: Upper Body Pull
Sunday: Rest

Each routine has positives and negatives, is dependent on how often you can work out, and is based on your preference! As long as your muscles are being forced to rebuild themselves stronger, and are able to recover before you work them out again, it’s the right workout for you.

While it’s possible to build out the perfect routine on your own, many of our Rebels end up spending hours and hours building something custom – only to realize it isn’t what they need (or isn’t effective) weeks and months later for their goals.

For people who want to avoid that altogether, we built the solution – pairs you with your own Nerd Fitness Coach who will get to know you, your goals, and your lifestyle, and handcraft a workout plan that’s specific to your body, your schedule, and your life.

How Many Sets and Reps Should I Do?

We have a (it’s where the video above comes from), but you can follow the basics here.

For beginners, we recommend starting in the 5 – 15 reps range to increase both size and strength. (If you want to focus on more strength than size, stick to the lower end of that range.)
As you get more advanced, you may find that it’s beneficial to do up to 30 reps of an exercise. (Though 90% of your work will still be in that 5 – 15 rep range.) The biggest drawback to higher rep ranges like this is it can be hard to target specifically that “1 to 3 reps before failure” when the rep count is so high.

The good news is that no matter which path you take (pure strength, size, or a mix of both), as long as you are adding weight each week – and eating enough – you WILL be getting stronger.

ANY path will work, provided you are progressively overloading your muscles with an increased challenge!

Coach Jim explains it all for you right here:

Progressive overload involves exerting slightly more effort than last time (lift a heavier weight or do 1 more rep) consistently.

Your muscles will have to adapt and rebuild themselves to get stronger. So in order to see improvements, your training must gradually and constantly increase.

We just have to make sure we get the right pace!

According to Mike Rebold, PHD, a professor from from Hiram College:

Keep in mind that if the overload increases too quickly, poor technique and injury may result. And if the overload progresses too slowly, improvements will be minimal or non-existent.

Slowly but gradually increasing your challenge could look like:

If you do 5 sets of 5 squats at 140 pounds this week, aim for 5 sets of 5 of 145 pounds next week.
Or if you’re doing 3 sets of 10 at 100 pounds, then next week try for 3 sets of 12 at 100 pounds.

Get stronger, which is 20% of the puzzle. The other 80% is nutrition (which I cover later)!

7 Muscle Building and Weight-Lifting Tips

#1) before exercising – don’t walk into a gym, slap 45-pound plates on the bar, and then start your routine.

Get your heart rate up and muscles warm first by doing a dynamic warm-up of jumping jacks, lunges, bodyweight squats, hip raises, push-ups, leg swings, jumps, etc, for a couple of minutes.

After that, always start with doing a set or two of lifting a much lighter weight than your planned heavy sets, gradually increasing your weight each warm up set until you are ready to start your workout proper. Only then should you start adding weight for some warm-up sets before moving into your work sets.

#2) Have a focused form – if you’re , you might develop bad habits.

However, if you incorrectly with 405 pounds on your shoulders, you could do some serious damage. If you’re just starting out, check your ego at the door: start with a VERY light weight and make sure you are doing the exercise properly.

There is NO SHAME in starting with just the bar. You can always add more weight next week if this week is too easy.

#3) Stimulate, don’t annihilate – I try to always have one more rep left when I finish a set.

While it can be helpful to occasionally go to failure in order to gauge how many “reps in the tank” you have left, this isn’t something we would do all the time.

Your muscles get built while resting, not in the gym, so don’t worry about destroying them completely each day you step in the gym – it’s not worth it.

#4) Adjust your rest time accordingly – some muscles take longer to recover than others. For example, your quads may need more rest time before they feel ready to do another set, while your shoulders may only take half the time.

You know you are ready to start the next set when:

You’re not so out of breath that it’s limiting your ability to perform the lift
You’re muscles are recovered enough to do at least 5 high quality repetitions (the bottom end of the 5 to 30 target rep range for muscle building)
You’re supporting muscles aren’t a limiting factor (for example, your biceps aren’t the muscle that is limiting your ability to do a back exercise)

For most people, this is going to be 30-90 seconds between warm-up sets and 2-3 minutes between working sets.

Just be consistent between sets and when doing the same workout between weeks to track your progress.

Bottom line: The most important thing is to rest long enough that you can give near the same level of effort as you did in the previous set.

For more, learn all about .

#5) Don’t overdo it – More does not mean better in weightlifting. You don’t need to spend two hours in the gym, you don’t need to do 15 different kinds of chest exercises.

My routines last no longer than 45 minutes, I only do three or four sets (after warm-up sets) for each exercise, and it’s enough to stimulate muscle growth. I only need to add more if my growth plateaus or stops, and before I do that I make sure my intensity, diet, and recovery are dialed in FIRST.

Three workouts a week is a great place for most to start – we’ve had clients build muscle on anywhere from 2 days a week to 4 days a week using a full-body routine like this! You need to give your muscles time to regrow bigger – remember muscles are made in the kitchen!

Less is often more – just make your routines really intense and exhausting.

#6) – Keep a training journal, and write down exactly how many sets and reps you did for every exercise.

That way, you can compare how you did this time with how you did last time. You’ll know how much more you need to lift this week to make sure you’re stronger than last week.

#7) Follow a routine, have a plan and stick with it for months and months. We are training our muscles to get stronger and stronger, so you’ll get the best results if you can fall in love with the boring process of doing the same workout – but lifting heavier weight for months and years.

I’ve been doing squats, pull-ups, deadlifts, and presses once a week, every week for 24 years. The sets, reps, and weights have changed, but the workout is largely the same. I don’t need to be entertained by the workout, I’m excited about, “how much weight can I lift?!”

How Many Calories Should I Eat ToGain Muscle (and Which Supplements)

If you’re , this will be 90% of the battle.

If you’ve been lifting weights for a while “but can’t seem to gain weight,” then you are not eating enough. To gain weight, you’re going to need to seek a calorie surplus (i.e., hypercaloric diet). This usually consuming an additional 250-500 kcal/day or 10-20% above your typical diet.

I thought I was one of those people who just could never gain weight, even after training hard for 6 years…and then I learned it was all diet, started eating 3500+ calories a day (lots more liquid calories, rice, bread, oats, and potatoes!), and .

After 6 years of exercising without putting on any weight, it was great to see so much progress in such a short period of time.

I’ve since changed my strategies and have become more calculated in my approach. It’s how .

So, as a former super skinny nerd who finally realized “it’s the calories, dummy,” here’s the 3-step process for nutrition when it comes to building muscle:

PART #1: Eat More – To gain weight, you’re going to need to seek a calorie surplus (i.e., hypercaloric diet). This by consuming an additional 250-500 kcal/day or 10-20% above your typical diet.

You can get an estimate of how much you need to eat to just MAINTAIN your weight in our

I’m not clairvoyant (yet), so I’m not sure how you’re currently eating. But if you’re looking to add more calories, there are 3 key places to look:

Adding more carbs: rice, bread, pasta, oatmeal, cereal, potatoes, and any other calorically dense food!
Adding more fats: avocado, olive oil, nuts, seeds, cheeses, nut butters.
Drinking more liquid calories: protein shakes (covered below), juice, milk, weight-gain shakes, etc.

Besides just seeking a calorie surplus, it can also be beneficial to pay attention to your macronutrient ratio (e.g., carbohydrates, fats, and protein).

For more specific information on what foods to eat and how to structure your diet for bulking, check out our !

PART #2: Eat enough protein – With all the hard training you’re doing, you want to not only gain weight but make sure your body has the resources to turn as much of that weight as possible into muscle.

That’s why we put together – so you can maximize your gains! For most people, targeting between 0.7-1.0g/lb of bodyweight gets you in the optimal muscle-building range.

In our , we discuss sources of protein and provide simple ways to incorporate more into your diet. If you’re not used to eating a lot of protein, that can be a struggle!

“Which Supplements Should I Take to Build Muscle Quickly?”

As we lay out in our , most supplements are a waste of money and completely unnecessary for building muscle.

However, there are two supplements that CAN BE helpful in building muscle quickly:

:If you are struggling to hit your protein and calorie intake goals for the day, adding in a high-calorie protein shake can be a game-changer.
: Creatine helps your muscles retain water and can improve your performance, allowing you to push harder, for longer, in the gym.

Bottom line: If you don’t see any change, then you need to eat more.

Yes, it will feel excessive.
Yes, you will feel full all the time.
Yes, it’s a pain in the ass and expensive.

But if you really want to be bigger, then you are going to need to really dedicate yourself in the kitchen.

Unless you’re a genetic mutant, it’s incredibly tough to build muscle and strength without overloading your system with calories and nutrients.

Just keep eating.

Won’t All of This Eating Make Me Fat? I Don’t Want to Get Bulky.

I have amazing news: as somebody who has been trying to get “too bulky” for 20 years, it’s unbelievably difficult for a naturally skinny person to suddenly get too bulky.

Yes, you will put on SOME fat along with the muscle you’re building if you’re running a calorie surplus.

This is why picking the right amount of calories per day is important:

If you can build muscle at 3,000 calories, but you’re eating 4,000 calories, you’ll put on a pound or two of fat per week along with your muscle.
However, if you need to eat 3,000 calories to build muscle and you’re only eating 2,500, you won’t see any changes.

Everybody is different, so you need to experiment and find out what works best for you.

Once you get to your desired weight (actually, aim for about 10-15 pounds heavier than your goal weight), you can scale back the calories, increase your step count, and keep lifting heavy – the muscle will remain, the fat will disappear, and you’ll be left with the body you want.

I’m not skinny, I need to LOSE weight – what’s different for me?

As Coach Matt explains above, you can actually build muscle and lose body fat at the same time.

You just have to be careful about how you do it.

We cover the subject in depth in the post, “”:

If you are eating enough protein, and have decent fat stores to pull from for energy needs, you can build muscle even while in a caloric deficit.

As long as you are resting () and strength training (), you can while still putting on muscle.

Now, this only works if you have plenty of fat stores to pull from. Once you start to lean out a little, you’ll likely have to increase your calories to start putting on more muscle.

Just remember, you can build muscle while losing weight if you:

Sustain a caloric deficit
Lift heavy
Prioritize protein
Rest

Let’s talk about that last one for a bit.

Rest Days for Building Muscle and Strength

As Coach Jim mentions in the video above, if you’re skinny and trying to bulk up and build muscle, avoid cardio like the plague (also avoid the plague).

Why?

Take a look at the best marathon runners in the world, and compare their physique to somebody like Usain Bolt, the best sprinter in the world – .

There’s nothing wrong with EITHER body – we’re all awesome and are special and blah blah blah.

But you’re reading an article about how to build muscle fast, right? So focus all of your effort on building muscle!

You want all the calories you’re consuming to go towards “building muscle,” and not “fuel my run.”

I will admit that I’m biased against chronic cardio, but mostly because it bores me!

You can be far more effective when you focus on getting stronger and only do ‘cardio’ on things you enjoy – after all, your success will largely depend on your nutrition, NOT your cardio!

If you’re lifting heavy, and eating enough, make sure you’re also getting enough sleep! 5-6 hours a night isn’t going to cut it – you need to get at least 8-9 hours of sleep per night for optimal muscle-building. Take naps too if you have the opportunity.

, because while we’re asleep, growth hormone, a hormone responsible for regulating muscle growth is released.

If you’re a big guy/girl trying to slim down, a little extra cardio might speed up your fat loss but if you’re not eating correctly, it might result in losing some of the muscle you already have.

Don’t worry about going for 10-mile runs on your off days – do 20-30 minutes of intervals or go run hill sprints in your park. The weight will come off more slowly, but you’ll be losing predominantly fat, not fat AND muscle.

Once you hit your goal weight and the target amount of muscle mass, I’d recommend adding back in some cardio for your overall conditioning and cardiovascular health.

If you love and aren’t going to give that up, I’m not gonna stop you. Just know that the long hours of cardio will severely inhibit your progress on building strength and size.

Get Started Building Muscle Today

This is a basic overview to get ya started. It really boils down to a few major things:

Lift heavy
Eat lots of good food
Rest

Simple to understand, tough to implement.

Trust me, I know – I’ve been battling this for the past decade.

Footnotes ( returns to text)

In order to stimulate muscle hypertrophy we need to break our muscles down. While engaging in strength training, microscopic tears are happening to our muscle fibers. This will stimulate the process of muscle hypertrophy. (Powers SK, Howley ET. (2011). Exercise physiology: Theory and application to fitness and performance. New York: McGraw-Hill Humanities/Social Sciences/Language).
The process of muscle hypertrophy is also facilitated by having enough amino acids (i.e., building blocks) circulating in our blood that can be assembled into contractile proteins (e.g., actin and myosin) through the processes of transcription and translation. For more, read “Increased rates of muscle protein turnover and amino acid transport after resistance exercise in humans.” Source, .
Adequate rest and sleep is imperative in order to have adequate growth hormone release, which assists in regulating muscle hypertrophy. For more, read and .
“No differences were detected in the direct comparison of strength, jump performance, and muscle hypertrophy between free weight and machine exercises. The current body of evidence indicates that strength changes are specific to the training modality, and the choice between free weights and machines is down to individual preferences and goals.” .
Read, “High-Intensity Functional Training: Molecular Mechanisms and Benefits.” Source, .
According to the National Strength and Conditioning Association (NSCA), for less trained people (i.e., beginners), it is recommended that for upper body exercises you increase the load by 2 – 5 pounds and by 5 – 10 pounds for lower body exercises. (Haff G, Triplett NT. (2016). Essentials of strength training and conditioning. Fourth edition. Champaign, IL: Human Kinetics).
The functional and compound exercises like a barbell squat will result in multiple muscle groups being stressed throughout the lift. This is also known as closed-chain exercises, in which the distal end of the extremity is fixed to a surface. Imagine performing the barbell squat. The distal end of the extremity being stressed are the feet and they are fixed to the surface. These exercises are more functional and allow us to understand how well we can perform in sports, recreational and occupational activities, and activities of daily living (Haff G, Triplett NT. (2016). Essentials of strength training and conditioning. Fourth edition. Champaign, IL: Human Kinetics).
“No differences were detected in the direct comparison of strength, jump performance, and muscle hypertrophy between free weight and machine exercises. The current body of evidence indicates that strength changes are specific to the training modality, and the choice between free weights and machines is down to individual preferences and goals.” .
Additionally, by following this type of routine you will ensure that you are training agonist (i.e., the muscle that contracts) and antagonist (i.e., the muscle that opposes the agonist muscle and relaxes) muscle groups and decreases your risk for developing muscle imbalances, which is what often is (e.g., knee-related injuries).
In this instance, lower body exercises are categorized as “push” – or front of leg, and “pull” or back of leg, and split up between these two days.
The simply recommends 8-12 reps for 2-4 sets for healthy individuals.
In general, to gain muscle mass you need to seek a calorie surplus (i.e., hypercaloric diet). This by consuming an additional 250-500 kcal/day or 10-20% above your typical diet. You may also need to increase your protein intake to 1.6-2.2 g/kg of bodyweight spread evenly throughout the day. And finally, carbohydrates should be the focus of the remaining calorie surplus demands when considering fat intake levels should remain at 20-35% of kcals.
A traditional warm-up consists of . The first is a general warm-up of 5-10 minutes of low- to moderate-intensity aerobic exercise, such as jogging or stationary cycling. The second is a specific warm-up that involves less intense movements similar to the sport or activity about to be performed. For the purposes of muscle building, this involves doing lighter variations of the exact movement you are going to perform. For example, if you are going barbell bench press with 135 pounds, you may start with a set a 45 pounds, then 90 pounds, then 115 pounds to warm up the tissues and practice your technique before moving on to the “work sets” at 135 pounds. The purpose of this type of warm-up is to allow the body to gradually adjust to the demands of exercise by allowing for increases in heart rate, blood flow, muscle temperature, and core body temperature. These gradual adjustments will result in enhanced performance and a decreased risk of injury.
Plus, based on , it is still unclear if strength training to muscular failure is really necessary to maximize increases in muscle strength and hypertrophy. A more recent investigation made the following conclusions: Strength training to failure is not necessary for increases in strength and hypertrophy. If wanting to perform strength training to failure, high-intensity strength training to failure is only recommended for trained individuals, while low-intensity strength training to failure is recommended for untrained individuals.
In other words, don’t stress this. The NSCA recommends 2 to 5 minutes of rest in-between sets or exercises for strength and power, 30 seconds to 1.5 minutes for hypertrophy, and 30 seconds or less for muscular endurance. While has a basic recommendation of 2 to 3 minutes.
According to the and the CDC, all healthy adults aged 18-65 years should participate in moderate-intensity aerobic physical activity for a minimum of 30-minutes on five days per week, or vigorous-intensity aerobic activity for a minimum of 20-minutes on three days per week. Additionally, every adult should perform activities that maintain or increase muscular strength and endurance for a minimum of two days per week. Performing exercise at a moderate-to-vigorous intensity will result in greater caloric expenditure and weight loss.
Also, spread it out if you have to! The have found that if you accumulate 10-minute bouts of exercise throughout the day that can be as effective as one who does one 30-minute bout of exercise.
And, don’t use your cell phone for other purposes besides using it to listen to music as other cell phone functions such as texting and talking have to lower the intensity of exercise resulting in lower caloric expenditure, and leading to a greater risk of musculoskeletal injuries.
The term here is “.” Periodization allows for the management of the adaptive and recovery responses from a training program to be delivered in a structured way to maximize physical improvements and to decrease one’s risk for injury.

As we mentioned above, when seeking a calorie surplus you will need to consume additional protein per day () and protein shakes can help you achieve those recommendations.
Skeletal muscle is the primary site of creatine storage accounting for up to 90% of the total body pool. The total body by the ingestion of foods high in creatine (e.g., meat and fish) or through nutritional supplementation. Creatine is important for the regeneration of phosphocreatine (PCr), which our body is able to use to generate energy (ATP) to support muscle contraction and lead to muscle hypertrophy. Chronic training with elevated levels of creatine has been found to result in increases in lean muscle mass, strength, and power. Creatine monohydrate, the most common form on the market, in solution has to increase whole body creatine to a greater extent than consuming meat.
Plant-based protein sources include soy products (e.g., tofu, tempeh, etc.), beans, lentils, nuts and seeds, and most grains (e.g., quinoa). Vegetarians about their complementary sources of protein (i.e., combining multiple plant protein sources to help improve delivery of essential amino acids [e.g., brown rice + green peas + corn]) to ensure they meet their daily needs of complete proteins and are able to attain all the essential amino acids that they need in sufficient quantities to support muscle hypertrophy.
Just keep the calorie surplus recommendations in mind that we keep providing to you within this article. Also, when selecting additional food to consume, make sure the calorie surplus is coming from protein and carbohydrate sources. The additional protein will be used to support muscle hypertrophy and the additional carbohydrate will be used to maintain your blood glucose and be converted to glycogen to support ATP production for your muscles.
A found that during a 40% calorie deficit diet, consumption of a diet containing 2.4 g/kg/day of protein was more effective than consumption of a diet containing 1.2 g/kg/day of protein in promoting increases in muscle mass and losses of fat mass when combined with a high volume of resistance and anaerobic exercise (exercise 6 times per week [2 sessions of resistance training, 1 session of plyometric training, and 3 sessions of HIIT cycling]).
Remember, ttwo main drivers of muscle protein synthesis (i.e., muscle hypertrophy) are strength training and ingestion of protein.
Read, “Physiology of growth hormone secretion during sleep.” Source, .
Endurance training results in both physical and chemical changes to muscle fibers that do not support hypertrophy. Typically, with endurance training what we will see within the muscle fibers is mitochondrial remodeling (increased concentration of capillaries, mitochondria, and myoglobin) allowing the muscles to be fatigue resistant and produce little force. (Oikawa SY, MacinnisMJ, Tripp TR, et. al. Med Sci Sport Ex. 2020;52(6):1394-1403).
