Patience is overrated, especially in the weight room and the kitchen, when there's typically a specific desired outcome for athletes: figuring out how to build muscle. And you’ll want to grow that muscle fast.

Sure, change takes time. But if you’re trying to find the fastest way to grow muscle and aren’t seeing obvious size increases from month to month, it’s a sign your approach is off. 

Plus, even if you are seeing progress, there’s no reason you can’t strive to see more muscular gains.

How do you rev up your results? Here are nine tips that will teach you how to build muscle.

How to Build Muscle (Fast)

1. Grow Muscle: Increase Your Training Volume

Training volume — your number of reps multiplied by your number of sets — is a primary determiner of hypertrophy (muscle volume growth). And to increase volume, you may actually need to go lower in weight than you might guess.

“Compared to training for strength, intensity is going to drop during the hypertrophy phase of a program, with intensity sitting between 50 and 75 percent of the person’s 1RM, the maximum weight he or she can lift for one rep,” says Ava Fitzgerald, C.S.C.S., C.P.T., a sports performance coach with the Professional Athletic Performance Center in New York.

To get the volume your muscles need, she recommends performing each of your lifts for three to six sets of 10 to 20 reps.

2. Grow Muscle: Focus on the Eccentric Phase

When lifting any weight, you will have a concentric (agonist muscle contracting) and eccentric (agonist muscle lengthening) phase. 

For instance, as you lower into a squat, you’re performing an eccentric action. When you return to standing, that’s concentric. And, according to research published in the European Journal of Applied Physiology, eccentric work is far better at triggering hypertrophy.

To increase the amount of eccentric effort in your workout, you can do two things: either slow down the eccentric phase of each exercise you perform or integrate eccentric-only variations into your routine.

Take the squat, for example. To make it eccentric-only, you would lower to the floor, and end the exercise there. Note: If you’re trying eccentric-only exercises, you’ll need to substantially increase the weight that you use. 

Physiologically, muscles are far stronger moving eccentrically than they are concentrically.

3. Grow Muscle: Decrease Between-Set Rest Intervals

If you touch your phone between exercise sets, it better be to set its timer to 30 to 90 seconds. 

When lifting for hypertrophy, rest periods of 30 to 90 seconds encourage a quick release in muscle-building hormones (including testosterone and human growth hormone) while also making sure that you really, truly fatigue your muscles, according to Fitzgerald.

Research published in the Journal of Applied Physiology last year suggests that, irrespective of rep and set scheme, fatiguing your muscles is a prerequisite for hypertrophy. 

Don’t be afraid to feel the burn.

4. Grow Muscle: Eat More Protein

Strength training breaks down your muscles, and protein builds them back up. The more difficult your lifting workouts are, the more important muscle-building foods become when weighing protein intake to solidify recovery, Fitzgerald explains.

According to research from the University of Stirling, for optimal muscle growth, weight lifters need to eat 0.25 to 0.30 grams of protein per kilogram of body weight per meal.

For a 175-pound person, that works out to 20 to 24 grams of protein at every meal.

You’ll get that in three to four eggs, a cup of Greek yogurt, or one scoop of protein powder.

5. Grow Muscle: Focus on Calorie Surpluses

This can be a hard one to get used to, especially for those who are used to counting calories in the hopes of shredding fat. But when it comes to how to gain muscle mass fast (that means weight gained, not lost), you need to consume more calories than you burn each day.

That’s because, when your body senses that it’s in a calorie deficit — meaning you’re consuming fewer calories than you’re burning each day — it downshifts your body’s tendency to build new muscle. After all, if your body thinks food is in short supply, getting swole isn’t going to be its main priority.

Aim to eat roughly 250 to 500 extra calories per day. To make sure that any weight gained is from muscle, Fitzgerald recommends that the bulk of those calories come from protein. 

In a 2014 Pennington Biomedical Research Center study, people who ate a high-calorie meal plan that was rich in protein stored about 45% of those calories as muscle, while those following a low-protein diet with the same number of calories stored 95% of those calories as fat.

6. Grow Muscle: Snack on Casein Before Bed

Long popular among bodybuilders, casein protein absorbs slowly into the bloodstream, meaning it keeps your muscles fed with amino acids for longer compared to other types of protein, such as whey and plant proteins. 

In one Medicine and Science in Sports and Exercise study, consuming casein protein immediately before bed boosted young men’s levels of circulating amino acids for 7.5 hours; they built muscle all night long while they slept.

To get some pre-bed casein, try cottage cheese, Greek yogurt, and milk. For smoothie lovers, casein-based protein powder works like a charm.

7. Grow Muscle: Get More Sleep

Muscle recovery requires more than the right nutrition. It takes time — roughly eight hours per night — dedicated to recovery, Fitzgerald says. After all, when you sleep, your body releases human growth hormone, which helps grow muscle and keeps levels of the stress hormone cortisol in check.

Plus, according to a study in the Journal of the American Medical Association, sleeping for five hours — as opposed to eight hours — per night for just one week cuts muscle-building testosterone levels by a whopping 10 to 15%.

The National Sleep Foundation recommends that adults ages 18 to 64 sleep seven to nine hours per night. No excuses.

8. Grow Muscle: Try Supplementing With Creatine 

Creatine doesn’t directly grow muscle. But by boosting your performances at high-intensity lifting workouts, the natural compound helps promote muscle growth, according to the Journal of the International Society of Sports Nutrition.

In fact, in one Journal of Strength and Conditioning Research review, researchers concluded that, at a given weight, supplementing with creatine can help you lift 14% more reps than you can sans supplements.

For the best results, opt for creatine monohydrate, the most thoroughly researched form of the supplement.

9. Grow Muscle: Add HMB

A natural compound produced in the human body, beta-hydroxy-beta-methylbutyrate helps prevent muscle-protein breakdown, encourages muscle growth, and speeds exercise recovery.

Unfortunately, it’s hard to significantly increase levels through food alone. That’s where supplementation comes in. 

For instance, in one 12-week study of resistance-trained individuals, taking HMB in tandem with a high-intensity lifting routine significantly improved muscle strength and size compared to lifting alone. 

Plus, in the off-chance that you push yourself too hard, HMB helps prevent the effects of overtraining — including muscle loss.

To boost your efforts to grow muscle, you can take HMB supplements solo or opt for protein and creatine powders that come with HMB baked right in.
