How to Build Muscle: Training, Recovery and Progress

In short

You want to build muscle, but where do you start: your workouts, your food or your recovery? Put all three together: a good workout plan, enough calories and protein, and time to recover. I also recommend tracking your weights and reps so you can see your progress.

Here is how I would approach building muscle mass, from the main principle to training, nutrition and the mental tips that help you stay with it. Let's start!

How to increase muscle mass: the main principle

When you train, your muscles work against a load they are not used to. After the workout, your body goes into recovery. It repairs and remodels your muscle fibers, and beyond the repair, it adapts to the load you put on it: over weeks and months, the fibers get bigger and stronger.

You may have heard that muscle grows because training makes tiny tears in the fibers. Training does cause some muscle damage, especially when a workout is new to you. But a 2018 review of the research argued that the damage is not what drives growth: programs that caused little damage built similar muscle and strength. So you don't need to feel wrecked or very sore after a workout for it to work. What matters is a hard, repeated training signal and enough recovery to adapt to it.

To build muscle mass, your body needs enough nutrients. For a bulk, I recommend eating more calories than you burn: this is called a positive calorie balance. The aim is to gain as much muscle as you can while keeping fat gain as small as possible.

Can you build muscle and lose fat at the same time?

Many coaches sell an "ultimate method" for gaining muscle and losing fat at the same time. Be careful with these offers. It can happen, but it is not a guaranteed result for everyone; your starting point and training experience matter (the nutrition review linked in Sources).

Your body still needs energy and building material. If something seems too good to be true, it probably isn't true.

Start with a medium/low body fat percentage

If your body fat percentage is already high, bring it down before starting a bulk. I wouldn't start by adding more food.

The more fat you gain during a bulk, the more you will have to lose afterward. My aim is to keep the process controlled, rather than turn the cut afterward into a long, exhausting project.

A common coaching belief is that starting at a lower body fat percentage makes the bulk more effective. That is why I recommend starting with a medium/low body fat percentage.

Eat enough calories to build muscle

How do you know what is enough? I would choose between two main approaches:

• Follow a meal plan.
• Estimate your portions and track your body weight.

Both can work. A meal plan is significantly more effective: it gives you a clear way to control your eating and aim for as little fat gain as possible. Estimating portions is harder to keep consistent.

But your lifestyle may not let you stick to a meal plan. Soldiers, police officers and people whose jobs make regular meals difficult are good examples. So what can you do?

Try to eat at regular times and keep your portions similar each day. Weigh yourself once a week and check whether your weight is going up alongside progress in training. A rise of around 250–500 grams a week can be a useful rough check, but I would compare it with the body-weight guideline below rather than use the same target for everyone.

Whichever approach you choose, make sure you get enough protein too. That is the next part.

Make sure you eat enough protein

Protein provides amino acids, the building blocks your body uses to repair and build muscle fibers. This is why I put enough protein alongside training and recovery, rather than treating it as an afterthought.

Protein also has many other roles, including building cells, supporting hormone production and the immune system, maintaining bones and providing energy (the protein review linked in Sources).

For building muscle, I recommend about 1.6–2.2 grams of protein per kilogram of body weight a day, as discussed in the nutrition review in Sources. For example, at 70 kilograms, that works out to 112–154 grams a day.

Reaching your daily amount is not always easy. Protein powder can be a convenient way to help, and I'll come back to it in the supplements section.

Track body weight

During a bulk, I want your weight gain to be controlled rather than rapid, so you gain as little fat as possible. The nutrition review linked in Sources suggests around 0.25–0.5% of body weight per week. At 70 kilograms, that is about 175–350 grams a week.

Hitting that number exactly is difficult. If you gain 500 grams in one week, I would not panic; I would look at the trend before making a change.

Body weight can vary because of fluid. Eating more carbohydrates or sodium before a weigh-in can change the number on the scale. Weigh yourself once a week and look at about three weeks of results, rather than judge one weigh-in.

Then I would adjust your food: add some if the gain is too small, and reduce it if the gain is too large.

Choose a good workout plan!

If the plan you put so much effort into isn't a good one, you won't build serious muscle, no matter how hard you work.

Building a workout plan is a whole art. It has countless elements: how many workouts a week, the right exercises, the number of sets, the number of reps, the order of the exercises, the mix of compound and isolation exercises, recovery time, and much more.

For most beginners, I recommend starting with a full body (FBW) plan: you train your whole body in each workout. After about a month, I recommend moving to a more advanced plan, such as an A/B or ABC split.

The training principles that build muscle

These principles apply to any muscle-building plan. They follow the 2026 position stand of the American College of Sports Medicine (ACSM), an overview of 137 systematic reviews with more than 30,000 healthy adults.

1. Progressive overload

Your muscles adapt to what you ask of them, so you have to keep asking for a little more. The ACSM position stand tells healthy adults to do progressive resistance training. In practice, that means adding a rep, a set or a small amount of weight over time, while your technique stays clean. The tracking section below shows a simple way to do it.

2. Enough weekly sets per muscle group

Count the hard sets each muscle group gets in a week. The ACSM position stand found better muscle growth with 10 or more sets per muscle group per week. An earlier meta-analysis of 15 studies (Schoenfeld 2017) found a graded relationship: more weekly sets went with more growth, up to the volumes those studies tested.

For example, if you do 4 sets of the bench press on Monday and 3 sets of push-ups plus 3 sets of the incline dumbbell press on Thursday, your chest gets 10 sets that week.

3. Effort: close to failure, not always to failure

A set builds muscle when it is hard. Most people do well when they stop a set with about 1 to 3 good reps left. A 2023 meta-analysis of 15 studies (Refalo) found no evidence that taking sets all the way to failure builds more muscle than stopping short, and the ACSM position stand found that training to failure did not consistently change results. Going to failure on every set mainly adds fatigue. When you push heavy barbell sets close to failure, use a spotter or safety bars.

4. Frequency: spread your sets over the week

A 2019 meta-analysis of 25 studies (Schoenfeld) found that when the weekly number of sets was the same, training a muscle more or less often made little difference to growth. For strength, the ACSM position stand favored at least two sessions a week. So training each muscle group about twice a week is a practical way to fit 10 or more sets without very long workouts. A split that trains each muscle group once a week can also work, as long as the weekly sets add up.

5. Reps and exercises

Many muscle-building plans use about 8 to 12 reps per set, with compound exercises (several joints, like squats, presses and rows) first and isolation exercises (one joint, like curls or lateral raises) after them. More on rep ranges and loads in the hypertrophy guide, and on heavy, low-rep work in the strength training guide.

If you want to build your own plan, I would start with how to make a workout plan and count your weekly sets per muscle group. For exercise ideas, see the best chest, back and leg exercises.

Don't neglect recovery

Your body builds muscle while you recover, not while you train. If you don't give your body enough time to recover, you won't build muscle, however hard you train.

Recovery has two main parts: your training load and your sleep.

The load comes straight from your workout plan. If you choose a plan that fits your level, with enough rest between workouts for the same muscles, this shouldn't be a problem.

Sleep

Lack of sleep affects your health far beyond the gym, but here I'll focus on what it means for building muscle. Too little sleep can hold back your progress in several ways:

• Hormones. In one small study, 10 healthy young men were allowed only 5 hours in bed a night for a week in a lab. Their daytime testosterone levels dropped by about 10 to 15%, and they reported less vigor each day (Leproult 2011). The study did not measure muscle.
• Energy, focus and performance. Too little sleep can leave you overly tired, make it harder to concentrate, and hurt your performance in the gym.
• Injury risk. In a survey of 112 adolescent athletes, those who slept less than 8 hours a night on average were 1.7 times more likely to have had an injury (Milewski 2014). This shows a link, not proof that short sleep caused the injuries, and it was not a study of adult lifters.

Aim for 7 to 9 hours of sleep a night. The American Academy of Sleep Medicine and the Sleep Research Society recommend at least 7 hours a night for adults. When you stick to it, you will likely notice a real difference in how you feel and train.

Track your progress in the exercises

For most people, the muscle they build goes hand in hand with progress in their lifts. Many people don't write down what they do in their workouts. When you don't log, you can't tell whether you are improving, and you can't fix your mistakes.

Log one or two exercises in every workout, preferably compound ones: the weight, the number of sets and the reps in each set. I would try to improve a little every workout. Even one more rep in the last set of an exercise is progress.

In the short term it doesn't look like much, but this progress adds up. After a number of workouts, you will look back and see how far you have come.

Example: adding weight over time

This illustrative log uses a rep range of 8 to 12. After all three sets reach 12 reps, the next workout uses a small weight increase. It is an example of progression, not a record of anyone's workouts.

Progress is rarely this smooth. Look at the trend over several workouts, not at one bad day. A one-rep max calculator can help you follow your strength in your main lifts.

Building muscle takes patience

Building muscle is a process that takes time. If it were quick and easy, everyone would be muscular and fit, and it wouldn't be as special as it is.

The 2018 review also argued that part of the size change in the first few sessions of training is swelling from muscle damage, and that more true muscle growth shows up only after more sessions. So judge your progress over months, not days.

Find your own way, one that also lets you enjoy the journey. It could be certain exercises, a type of cardio you like, or a training partner. Sometimes the small things make a huge difference along the way.

Set specific goals

Set yourself very specific goals and write them down. The more precise your goal, the easier it is to work toward. For example, gaining 3 kilograms of muscle mass or reaching a certain weight in a certain exercise.

I would choose a goal you can realistically work toward in the near future, not a far-fetched one. Once you reach it, set a new goal. This way you progress step by step toward your big goal.

Supplements for building muscle

You don't have to take supplements, but they can help with a particular need. Understand what a supplement is for before buying it. Here are the options I would consider for building muscle mass, also discussed in the nutrition review in Sources.

Protein powder

Protein powder is a supplement, usually flavored, that contains a lot of protein. In a busy lifestyle, reaching your daily protein amount can be difficult. I see it as an available, convenient and often inexpensive way to make that easier.

Creatine

Creatine is an excellent supplement with a substantial research base. It helps your muscles replenish ATP, the compound that supplies energy for muscular work (the nutrition review in Sources).

When you lift a heavy weight quickly, your muscles use ATP. Creatine supplementation helps increase the stores used to replenish it, supporting that energy supply during training.

Gainer

A gainer is similar to protein powder, with added carbohydrates and more calories. It is intended for people who find it hard to eat enough calories or gain weight. I would choose it for that need, rather than simply because it is sold for building muscle.

Safety

Before lifting, set the safety arms or arrange a spotter for barbell squats and presses, secure the plates with collars, and adjust machine seats and pads to fit you. Warm up with light sets of the exercise before moving to your working weight. Keep each rep controlled, including the lowering phase, rather than rushing to reach your rep target.

End the set if you feel pain or dizziness, or if your form starts to break down. Leave time for recovery between workouts for the same muscles, protect your sleep, and go lighter or do fewer sets when you are still tired from the last session. For this muscle-building plan, use your log to add reps first, then make a small weight increase once you can complete your target reps in every set with the same clean technique.

Bottom line

If building muscle is your goal, I would focus on a good plan, enough food and protein, recovery and steady progress in your exercises.

Keep the process controlled and avoid eating endlessly just because you are bulking. Gaining unnecessary fat can make the cut afterward longer and more exhausting.

Building muscle isn't simple, and there are many things to take into account. I would start with a plan you can follow, record what you do, and make small adjustments as you go.

Frequently asked questions

How long does it take to build muscle?

It depends on you and your training. Judge your progress over months, and use your training log to see whether you are on track.

How many days a week should I train to gain muscle?

Two to four days suit most people. What matters most is about 10 or more hard sets per muscle group a week; training each muscle group about twice a week makes that easier.

Can I build muscle at home?

Yes, if your exercises are hard enough and you can make them harder over time, for example with dumbbells, bands or harder body-weight variations. See home workout exercises.

Do I have to train to failure?

No. Stopping most sets with about 1 to 3 good reps left works well, and reviews found no clear extra growth from always going to failure.

How can I build muscle fast?

There is no shortcut. Follow a good plan, count your weekly sets, add a little over time, sleep at least 7 hours and stay consistent. Be wary of anyone who promises fast results.

Do I need supplements to build muscle?

You don't have to take supplements to build muscle. Identify a need first: protein powder for convenience, a gainer for calories, or creatine to support your training.

Can women build muscle with the same principles?

Yes. The training principles in this guide apply to adults of any sex.
