The Best Science-Based Lower Body Workout for Growth

If you’re looking for a lower body workout that adds more size and symmetry to your lower body muscles, then you need to read this article.

This article is a continuation of my “upper body workout” post where I discuss how to best set up your upper body workouts. In this article however, we’ll cover how to set up your lower body workouts based on current scientific literature and our understanding of the lower body muscles.

The main goal of your lower body workouts should be to train your lower body muscles in a balanced manner. This not only makes your lower body look more aesthetic and proportional, but it also greatly decreases your risk of injury.

So how do we do this? Well, we do this by adequately training the following muscles: the quadriceps, hamstrings, glutes, and calves.

These are the main muscles that will contribute to the “aesthetic” of your lower body – and each muscle should be strengthened and grown in proportion to the others. But in order to accomplish this, we need to pick the right exercises.

So without further ado, let’s take a look at what the optimal lower body workout might look like.

Exercise 1 – Barbell Back Squats (Quadriceps Emphasis)

When it comes to quadriceps development, squats are going to be your best bet. Although squats will heavily involve the glutes as well and will definitely contribute to their growth, they have been repeatedly shown in numerous studies to elicit very high quadriceps activation when compared to other exercises.

And given that squats are an exercise that can be easily and effectively overloaded with weight, I’d highly suggest including them in your lower body workout.

As for whether to perform back squats or front squats, I’d suggest using back squats on one of your lower body days and then perform front squats on your other lower body day. Another option is to rotate between them overtime if you only perform one lower body day per week.

This is because although research shows that overall quadriceps activation is very similar between the front and back squats, research also shows that front squats may better activate certain quadriceps muscles that aren’t as well activated during the back squat.

For example, this table from a study from the journal of strength and conditioning research shows that certain quadricep muscles like the vastus lateralis and the rectus femoris are less activated during the back squat and moreso in the front squat.

Thus, for more balanced and full quadriceps development, it’s probably a good idea to incorporate both the back and front squat in your weekly routine.

Exercise 2 – Romanian Deadlifts (Hamstrings/Glutes Emphasis)

This next exercise is a variation of the traditional deadlift. Although the muscles worked will be quite similar between the two variations, Romanian deadlifts will put more emphasis on the hamstrings and glutes. This is because the knees are kept relatively straighter throughout the movement.

One 2014 study from the Journal of Strength and Conditioning Research compared hamstring activity in 4 different hamstring exercises – Romanian deadlifts, leg curls, glute ham raises, and good mornings.

Of the 4 exercises, Romanian Deadlifts and glute ham raises came out on top. Since Romanian deadlifts allow greater weight to be lifted and are easier to progressively overload overtime, I’d highly recommend including them in your lower body workout to strengthen the posterior chain.

And in terms of form, you want to perform them similar to how you would a traditional deadlift but instead keep your legs relatively straight throughout each rep. This is done by pushing the hips back and keeping your lower back straight as you lower the weight.

How low you go will depend on your mobility, but generally aim for below your knees and then contract your hamstrings and glutes to push the hips forward as you bring the weight back up.

Exercise 3 – Bulgarian Split Squats (Quads/Hams/Glutes Emphasis)

bulgarian split squat anatomy

As shown in my leg workout article, the Bulgarian split squat is something I think everyone should incorporate somewhere in their routine. They do a great job of hitting all the major leg muscles but with more emphasis placed on the posterior chain.

One 2010 study from the Journal of Sport Rehab found that the Bulgarian split squat more heavily involves the hamstrings and glutes than the back squat. In addition, one 2016 study by Speirs and colleagues suggests that the Bulgarian split squat may be just as effective at increasing back squat strength as the back squat itself – while placing less strain on the lower back!

Therefore, it’s clear that the Bulgarian split squat is a great complimentary exercise to use with squats for both muscle and strength development.

And the fact that it’s a unilateral exercise (meaning just one leg is worked at a time) helps prevent muscle imbalances from developing which is likely to happen if you only stick to bilateral exercises like the squat and deadlift for example.

Another important thing I want to mention regarding this exercise is foot placement.

One 2014 study from the Journal of Applied Biomechanics showed that a longer step length, such that the shin is vertical, makes the split squat more hip-dominant meaning that more emphasis is placed on the hamstrings and glutes.

Whereas a shorter step length makes the split squat more knee-dominant, meaning that more emphasis is placed on the quadriceps.

So you can apply this information in your lower body workout by either taking a longer step if you want to target more of your hamstrings and glutes, or take a shorter step if you instead want to put more emphasis on your quads.

Exercise 4 – Glute Ham Raise (hamstring emphasis)

glute ham raise exercise

This last exercise is something I’m personally a big fan of (and the literature seems to be as well)! It will put the most emphasis on the hamstrings but will also involve other posterior muscles like the glutes and lower back.

Now we already know glute ham raises are great at activating the hamstrings when compared to other hamstring exercises based on the results of the 2014 EMG study I mentioned earlier.

What this study also illustrates is that glute ham raises compliment Romanian deadlifts very well in terms of hamstring development. They found that although activation of one of the hamstring muscles (the long head of the biceps femoris) was maximized in both exercises, activation of the other two hamstring muscles was not. They were activated the highest concentrically (the way up) during the glute-ham raise and highest eccentrically (the way down) during the Romanian deadlift.

Simply meaning that it would be a good idea to include both in your routine.

This idea is further supported by a 2015 study from the Journal of Strength and Conditioning research. The researchers found that activation of the upper hamstrings can be maximized with hip dominant exercises (e.g. Romanian deadlift), whereas activation of the lower hamstrings seems to be maximized with more knee-dominant exercises.

lower body anatomy

This makes sense since the short head of the biceps femoris only crosses over the knee joint, and therefore can only be trained through knee flexion.

Therefore, including both a hip-dominant hamstring exercise like the Romanian deadlift AND a more knee-dominant exercise like the glute ham raise is recommended. This not only helps with balanced development of the hamstrings, but also contributes to injury prevention (especially in athletes).

And in terms of form, check out this tutorial I made via Instagram. I’d also appreciate it if you gave me a follow on there!

Now for those who don’t have a glute ham raise machine available at your gym, one knee-dominant alternative I’d recommend are leg curls on a stability ball. Additional alternatives are listed in the PDF mentioned at the end of this article.

Sample Lower Body Workout

So to sum up the video, here’s what your lower body workout could look like:


Barbell Back Squat: 3-5 sets of 6-8 reps

Romanian Deadlift: 2-4 sets of 8-10 reps

Bulgarian Split Squat: 2-4 sets of 6-10 reps

Glute Ham Raise: 2-4 sets of 8-12 reps

Standing Single Leg Calf Raise: 2-4 sets of 6-10 reps

Seated Calf Raise: 2-4 sets of 10-15 reps


I’d also advise adding in one or two calf exercises as well. I’ll be covering calves in more detail in a future article. Beginner lifters should probably stick to the lower end of the volume recommendations. Whereas more intermediate lifters should probably stick to the higher end of the volume recommendations.

And as I’ve done with my upper workout video, I’ve compiled all of this information into an easy to follow free PDF so that you guys can have it when you’re at the gym. It shows you the full workout, how to set up two lower body days per week, exercise tips with visuals, a progression scheme to use, and more. To get a copy of this, simply follow this link!

  1. Jeremy, thank you so much for your efforts. Your upper lower split helps me a lot.
    I just had one question, with which exercise i will train my lower back ? The deadlifts are just for the hamstrings and the glutes, right ?

  2. I have disc prolapse .. I am stable now .. But When I do bodyweight squat, i find it challenging and my lower back gives me pain.

    My question:
    Is it possible to drop the barbell squat (for safety and avoiding pain) without losing the hypertrophy benefits?
    Do I need to Adjust something in the workout routine?

  3. Hi Jeremy
    Just starting to train with weights again after 3yrs of doing nothing just wanting advice of what training split can you recommend for me
    I’m 52yrs old male
    Kind Regards Jimmy Flucker
    Dundee Scotland UK

    1. Start with the upper/lower workouts I have listed and ease your way into them in terms of volume/intensity.

  4. Your blog has been a fantastic learning tool for me and I love all the research backed evidence you provide. Thanks for providing such quality information and the free PDFs! I really enjoy your content!

  5. Hello Jeremy, you are totally awesome and selfless to he soo helpful. Your info is so helpful you cant imagine how much. As a male I want to lose my butt and obviously I dont want my butt to grow but I know how vital the weighted squats are. So does squatting make them grow bigger or removes inches? Really confused with all the conflicting information.

    1. Jeremy Ethier

      Thank you! Squatting will help grow your butt. If you want to grow your legs without growing your butt, it’s very difficult to do but leg press would be a better option

  6. Hey jeremy!

    You wrote in your PDF that it’d be a good idea to include rack pulls above the knee to one of my upper workouts if I want to do only Romanian Deadlifts in my routine. Will this affect my recovery much? Also, what set x rep scheme should I use for the rack pulls?

    1. Jeremy Ethier

      It shouldn’t as long as you’re managing volume. For rack pulls, I’d suggest 3-4 reps for 6-8 reps (heavy weight).

  7. Hey Jeremy!
    I am a little confused with calorie deficit. what is it about the incoming energy is smaller than the energy out? for example: i eat 2000 calories in a day, then i spent 2500 energy from the gym and cardio, so i deficit the calories 500, is it like that?

  8. Lower split #1:(with number of sets and reps the same as yours)
    1.Barbell Back squats
    2.Romanian deadlift
    3.Weighted hip trust
    4.Standin single leg calf raise
    Seated calf raises
    Lower split#2:
    1.Barbell/Dumbell front squats -3sets×12-15reps
    2.Bulgarian split squats
    2-4 sets×8-10reps
    3.Glute ham raise/Leg curls
    2-4 sets×8-12 reps
    ***Third exercise optional
    4.Single leg calf raises 2sets×8-10
    Standing calf raises 2×20reps
    Want to hear your thoughts on this schedule??

    1. Jeremy Ethier

      Front squats and split squats or reverse lunges all target the quads with less stress on the knee compared to other exercises.
