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
3. Lat Pulldown 5 8
4. Cable Row 3 12
5. Pull up 3 10
6. Hyperextension 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.

Hi Alboy, if you can do two more reps than what is listed, go heavier.

I have been following this program for 4 weeks so far and have packed on more muscle mass in that time than on any other program. Great routine, thanks M&S!

Hi I have two questions please.

1. I am 5’10 and 225 pounds currently on diet to lose weight My calf and legs are big genetically. For day 1 workout for legs will the workout help make my calf skinner or making them bigger ? As I’m trying to make them skinner.

2. I’m assuming each workout I need to finish all the sets before moving to the next workout right ? Like there isn't any supersets?

Thanks in advance

Hey there, Rany.

1. Skip the calves because if you already have genetically big calves, they will likely grow.

2. Yes, finish all sets before moving on. No supersets.

Hope this helps!

This is meant to help you add size, actually. But, if you diet correctly, then you could see yourself getting leaner.

If you're eating and doing cardio for fat loss, then you will be fine.

I’m going to give this program a try, I get most of my workouts from you guys, what weights should I use? Shall I pyramid every exercise I stay at the same weight for that workout and next workout progressive overload?

M&S Team Badge
Roger
Posted on: Sat, 09/23/2023 - 13:36

You can work this one with either style, Danny. I would personally opt for progressive overload, but your strategy of alternating would be solid as well. Good luck, and thank you for reading M&S!

Just about to start the program.
Should I do it as 4-day straight (Mo - Thu) or 2 days (Mon-Tue), a day off (Wed), and 2 days (Thu-Fri)?

Hi there!
First of all, I love your program. It has been working out so greatly for me.
In Day 3: Back, pull ups are the 5th exercise out of 6, and they are also the hardest.
Since they are the hardest, should I do them first, or wait to do it for my 5th exercise? Pull ups are the 5th exercise out of 6 for back day and when I get to it, I already used up my energy on other exercises. If I did them first, I could put on less weight (less weight makes it harder to do assisted pull ups)

M&S Team Badge
Roger
Posted on: Sat, 09/23/2023 - 13:30

Hi, Joseph. If pullups are a priority for you, then make them first. That is the move I would make as well. You can take them on when you have the most energy and capable of doing more. Good luck!

Hi there.
Been doing the lean muscle programme for a while now. Got great results. Now I want to build bigger lean muscle. Thinking of changing it up. Instead of doing say bench press 4 x 10 reps at 50kg. Do 4 x 8 reps at 60kg / dumbell lateral Raise 3 x 12 at 10kg do 3 x 10 at 15kg. Does this make sense? Is this the correct path to achive larger lean muscle?
Kind regards Andrew

Posted on: Thu, 04/06/2023 - 09:29

Hello, Andrew. That could possibly work. The extra resistance will help, and you're still in a good rep range for building muscle. I say go for it! Thanks for reading M&S.

Sometimes I am unable to do the exercises on the given because the machines are occupied. I also don’t like lingering around the machine and staying idle in the gym.
Is it necessary to follow the same sequence as you’ve provided ? Any recommended sequence if I have to mix them ?

Do what you gotta do to get the job done. If you need to change the order or swap a similar exercise in, go for it.

Hi Josh. Just completed the 6 wek program. Very happy with the results. Just wondering if I continue on could I change some exercises up. Say do dumbell curls instead of rope cable hammer curls. Maybe cable triceps press instead of seated french press? Look forward to your advise.

Cheers Andrew

What cable row should u do upper back with bar close grip grip etc ? Also should u complete the exercise in that order top to bottom

M&S Team Badge
Roger
Posted on: Wed, 11/02/2022 - 08:10

Use any attachment and grip you like. I prefer to use a rope attachment so I can spread the ends apart during the pull and get a greater contraction.

Also, in the future, you only need to submit your question once. It has to be approved before it is answered. Sending it multiple times won't help.

On the 4th day is it better to do overhead tricep extensions
Then Seated French press

M&S Team Badge
Roger

They are very similar. I prefer to do the dumbbell overhead extension myself, and there is also the cable option. Do the version you feel is best for you.

Josh Hi I thought naturals should hit each body part 2-3 times a week . Here your only hitting a bodypart once a week. What’s your take and also is there a way to turn this program into a upper lower split. Thanks

Roger
Posted on: Wed, 10/05/2022 - 20:44

Hi, Steve. There are several upper and lower splits available here on M&s if that would be your preference. I can't speak for Josh on this, but I can tell you from my experience that training each muscle group once a week is plenty if you train hard enough and recover properly.

Irving Campos Lugo
Posted on: Sun, 10/02/2022 - 12:34

Why the triceps only get 2 exercises on their own day, I get that doing chest activates the triceps as secondary muscle group but it seems not enough triceps activation on its own day

The last sets should be heavy for sure. If you're able to increase weight from week to week, go for it. Just don't beat yourself up if you need the same week. As long as you're giving your best effort, you'll be fine.

I really want to try this workout but I want to be clear what it means by 2/0/2? I'm guessing that means 2 sec up 2 sec hold and 2 sec release. Just want to be sure.
