Workout Description

When it comes to fitness goals, building lean muscle is among the most popular (seriously, 84% of our readers said so in our fitness survey).

And honestly, it should come as no surprise.

As a society, we glorify those who are lean, shredded, and have solid physiques with plenty of muscle mass.

So much so that a lot of us aspire to build lean muscle ourselves.

Well, today you’re in luck. Below is a 6 week workout program that will help you build lean muscle.

Check it out, read its description, and let us know if you have any questions in the comments section below!

The Workout Program to Build Lean Muscle

The following workout is a 4 day split you can follow for the next 6 weeks to build lean muscle. It is written to focus on increasing hypertrophy by performing 2-4 exercises for each muscle group during that muscle’s training day, for 3-5 sets, and 6-12 reps (although we’ll keep everything 8+ here).

The rep tempo should be slow as time under tension plays a huge role in the amount of muscle damage that occurs during each exercise, a factor that is critical to building lean muscle. Aim for a 2/0/2 tempo and really try to focus on the muscle you’re targeting during each lift.

Lastly, rest periods between exercises and sets should be kept fairly short. You’ll want to keep it between 30-60 seconds of rest after each set, with 45 seconds being the sweet spot.

Day 1: Legs

Exercise Sets Reps
1. Squat 4 10
2. Machine Hack Squat 3 12
3. Stiff Legged Deadlift 4 10
4. Leg Curl 3 12
5. Dumbbell Lunge 3 8
6. Leg Press Calf Raises 3 12
7. Seated Calf Raises 3 12

Day 2: Chest & Biceps

Exercise Sets Reps
1. Bench Press 4 10
2. Incline Bench Press 3 12
3. Cable Crossover 3 12
4. Hammer Strength Chest Press 3 8
5. Barbell Bicep Curl 4 10
6. Rope Cable Hammer Curl 3 12
7. Preacher Curl 3 10

Day 3: Back

Exercise Sets Reps
1. Deadlift 4 10
2. Barbell Row 3 12

The Workout Program to Build Lean Mass FAQs

Below are a couple of the more frequently asked questions when it comes to building lean muscle.

If your question is not listed below, please don’t hesitate to ask us in the comments section following the article.

Q. Can I add exercises to this workout program to build more lean muscle?

You certainly can, but it is not necessary. Each muscle group is targeted with a fair amount of volume within this program.

Adding more exercises to the program probably won’t increase the amount of success you have with it. Building muscle takes time. After 6 weeks of this program, you’ll likely notice a fair amount of muscle growth, but fitness goals should be long term, not short sighted.

Q. What should I do after I finish the 6 week workout program?

After you have finished this 6 week workout program to build lean muscle, I’d recommend taking a week to deload.

Enjoy a little time away from the gym; I promise 1 week won’t be enough to lose all the gains you’ve made. During that time reassess your goals and celebrate the amount of lean muscle you’ve put on in the past 6 weeks.

If you want to continue on with the program after your deload week, you’re more than welcome to. Or your goals might change. In that case, check out our workouts database for a new routine.

Q. How should I eat during this workout program to build lean mass?

This will depend on your starting point. I always recommend people get to a healthy weight range for their body type. If you’re overweight and a beginner to hypertrophy based training, you might benefit from starting off in a calorie deficit.

If you’re underweight, or an otherwise intermediate-advance lifter, you’ll likely need to be in a calorie surplus to add on lean muscle mass.

After you’ve determined which is best for you, find your calorie needs using our bmr calculator.

Then, subtract or add ~250-500 calories from that number to put yourself in a deficit or surplus. Make that your new daily calorie goal and try to get there by eating your calories through whole food, nutrient-rich food sources.

Workout Program to Build Lean Muscle Supplements

Q. What kind of supplements should I take with this workout program to build lean mass?

Supplementation is going to be highly individualized.

If you struggle to meet your daily protein needs, a solid protein supplement will be extremely beneficial to you.

If you struggle to meet your daily calorie needs all together, then a mass gaining supplement could be beneficial to you to help you accomplish your goals.

One supplement that is cheap, effective, and backed by a lot of scientific research is creatine monohydrate.

Q. Can I do some extra workouts on my rest days?

Again, you can, but I wouldn’t recommend anything to strenuous. Recovery is crucial to the muscle building process.

If you’re going to do anything, do something light that you enjoy doing. I highly recommend recovery walks as a form of active recovery. You could also hit the foam roller and work on the mobility that is often lost during muscle building programs.

Q. Where are the abs?

Your abs are hit indirectly quite frequently with this program during all of the compound movements.

Since they are worked indirectly almost every training session, I don’t feel the need to target them with isolation work. If you find it would be beneficial to do so for your training goals, you’re more than welcome to check out our ab workouts database.

Also, it is important to note that compound exercises and lowering your body fat percentage is going to build a better, visible 6-pack over time than any amount of direct isolation work will.

Q. Anything else we should know to build lean muscle?

Building muscle takes a lot of time and effort. Not to mention, what you do outside of the gym is just as important as what you do inside of the gym.

Prioritize your diet. Get 7-9 hours of sleep each night. Eliminate unnecessary stress (meditate). And move every day (lightly on your recovery days).

You’ll get there and this 6 week program is an excellent start.

Should we decrease 5 lbs for each set throughout the workout? What's the protocol for that? E.g. Curls: 40, 35, 30

Try to use the same weight for all sets, Thomas. If you need to reduce weight because you can't complete a set, that is okay and you should.

Frank

Should I add weight to the exercises each week (2.5-5%) to increase strength/get bigger?

M&S Team Badge
Roger
Posted on: Sun, 03/13/2022 - 19:52

What's good, Frank? If you can complete the set without compromising form, then jump 2.5% at a time. Slow and gradual jumps will help you make consistent strength gains as opposed to jumping 5% at a time and possibly hitting a plateau sooner.

I just finished week one of this set. Thanks for posting, it's been great so far.

I'm having a hard time keeping my back against the chair when doing the seated french press. I kept the weight lower than I'd normally go for. It may be a mobility issue. Any tips on getting better mobility in my back + shoulders? Any suggestions on replacement exercises?

M&S Team Badge
Roger
Posted on: Mon, 01/03/2022 - 20:11

Hi, Joe. Try placing your feet closer to yourself and planting them firmly before you start the set. Having the feet forward can lead to you driving your upper shoulders back, which would lead to your back becoming disconnected. Also, focus on sticking your chest out more. This could also be a cue that helps.

Posted on: Mon, 11/22/2021 - 18:40

Hey, Charles. They should be performed in order, but yeah, sometimes things don't work out like that. (See what I did there.)

Change the order when necessary, but keep in mind the weights you use could be different.

I have a problem with a tendon or ligament on the upper, back of my elbow (not lower, like tennis elbow), that prevents me from being able to do dips. Dips are the only triceps exercise that I can't do. Is there something I can do instead of dips?

Hey Aaron, go for single arm pressdowns or neutral grip dumbbell presses with the dumbbells over the chest. Hope this helps.

Hamza
Posted on: Sun, 08/22/2021 - 18:52

How do I pick a weight that is appropriate for the rep ranges that are specified for each exercise? And how far should I push myself in each exercise? For example, if I am able to complete the first exercise of a day successfully but that tires me out and I am unable to complete the rest of the exercises, that would be bad, but also if the weights are too light it would end up being ineffective. I’m just wondering how I would go about finding that balance.

M&S Team Badge
Roger
Posted on: Wed, 09/08/2021 - 15:41

Hi, Hamza. Thanks for the comment. This is a matter of simple trial and error. Choose weights that you're confident that you can handle for the reps required. Then take notes of how easy or difficult it was. The next time you do that workout, adjust the weights accordingly. If 50 pounds was very easy, go up to 60. If 50 was hard and you didn't finish, go back to 40. Hope this helps you out.

Hamza

Should I be going to failure in every set? Will doing so harm my performance in the subsequent exercises?

M&S Team Badge
Roger
Posted on: Thu, 05/19/2022 - 20:29

I wouldn't recommend going to failure on more than the last set on each exercise, Hamza. Going all out on each set will affect you later on in the workout.

Hi ! I have skinny legs and wanted to know if I want to bulk them more, should i work them twice a week instead using one of the rest days? Or will that not make much of a difference?

Posted on: Wed, 08/04/2021 - 20:29

Sandra -

The program is written to focus on increasing hypertrophy by performing 2-4 exercises for each muscle group during that muscle’s training day, for 3-5 sets, and 8+ reps. You can certainly add extra exercises, but it is not necessary. Each muscle group is targeted with a fair amount of volume within this program. So we recommend following the workout as written.

hi! im new to fitness and im trying not to bulk and I wanna lose fat on my arms and abs. I've heard that you cannot spot reduce fat and that you need to work all parts of the body in order to lose fat in the targeted area too. i don't want to lose weight but I want to build muscle and look lean. so if i eat in a calorie deficit and do this workout, will it help that?

Posted on: Wed, 06/30/2021 - 10:04

Hey sara - since you're new to training, I'd eat in a very slight caloric deficit or even at your maintenance calories. Doing a 3x per week full body strength workout is ideal for beginners. Once you run through a program like that for 8-12 weeks, you can move to a push/pull/legs or an upper/lower split.

Hey Agni - reducing body fat, especially being so lean already, is highly dependent on your diet.

I have one more doubt is it more difficult to reduce to 13% body fat ?
By just building the lean muscle will I be still able to reduce the fat to 13% ?
