Shoulder Workout for Mass and Symmetry (10 Studies)

best shoulder workout for mass thumbnail

Well developed shoulders are key to completing a balanced physique and getting that broad-shouldered look everyone is striving for. However, many people neglect to focus on all three heads of the deltoid muscle. And that is a huge mistake.

Proper development of all three portions of your shoulder is what gives them that 3-dimensional look. Which is why neglecting all three heads is detrimental.

Don’t believe me? Here are some recent shots of my personal development:

Shoulder workout progress

As you can see, it’s the balanced development of the anterior, lateral, and posterior deltoid that gives my shoulder that full look.

Shoulder Anatomy

To better understand this, let’s take a look at their anatomy.

shoulder workout anatomy

Similar to the 3 tricep heads, the deltoid muscle is divided into 3 main parts. The anterior, lateral, and posterior heads. Also commonly referred to as the front, middle, and rear delt.

Note that all 3 heads will be activated to an extent during all shoulder exercises. But as made evident in the literature, each head can be emphasized through the use of specific exercises and the way you perform them.

So in this article, I’m going to show you a shoulder workout optimized based on:

  1. Current scientific literature
  2. And our anatomical understanding of the delts.

But before we do so, let me briefly talk about the front delts.

Is Front Delt Isolation Needed?

As I previously mentioned it’s important to consider all 3 heads of the shoulders. But keep in mind that the front delt already gets sufficient indirect work through several pressing movements.

This is because the anterior deltoid is already very active in exercises like the bench press.

Also, as shown in these two studies by Trebs and Lauver, its involvement in pressing movements increases significantly as the level of incline increases.

So, you’re likely already performing a lot of flat and incline pressing movements that involve the anterior deltoid. Therefore, it’s better for you to focus more on the development of the lateral and posterior heads. These are the two groups that are commonly neglected in a routine.

unbalanced vs balanced shoulder

This not only helps balance your shoulder aesthetically, but as shown in this study by the journal of clinical biomechanics, “strengthening the posterior head of the deltoid is desirous for ensuring shoulder joint integrity and reducing injury potential.”

Thus, in this routine, we’re going to put more emphasis on the lateral and posterior heads of the shoulder.

Also, keep in mind that the four rotator cuffs are important muscles that shouldn’t be neglected. Why? Because they help stabilize the shoulder. But I’ll make a separate post for them.

Exercise 1: Overhead Press (Emphasizes Front + Lateral Delt)

The overhead press is an essential compound movement when it comes to shoulder training. This is due to the ability to easily overload it with weight and target all deltoid heads. There are several variations of this exercise which I will discuss. But note that they all mainly target the anterior deltoid with some involvement of the lateral and posterior heads.

In addition, the standing overhead press will also put more emphasis on the core musculature and serratus anterior muscle.

The Benefits Of The Overhead Press

This exercise has been shown in studies like this one by Behren & Buskies to be the best exercise for the anterior deltoid.

shoulder workout study

In fact, it was even shown to outperform dumbbell front raises by 41%. Thus I’d argue it’s the only exercise you need to include in your regimen that emphasizes the front delt.

Now as for which variation is most effective, you basically have four options:

  1. Barbell standing overhead press
  2. Dumbbell standing overhead press
  3. Seated barbell shoulder press
  4. Seated dumbbell shoulder press

Different Overhead Press Variations

shoulder press workout options

This study from the journal of strength and conditioning research compared the 4 variations. It found that compared to any of the other conditions, the standing dumbbell press elicited higher:

  1. Anterior,
  2. Lateral,
  3. And posterior deltoid activation

Opt For The Barbell Overhead Press

So it may seem that research suggests this variation is the best. But I think that it’s a difficult exercise to overload. This is especially once you get to very heavy weights.

For this reason, I’d opt for the barbell overhead press instead. It wasn’t very far behind the standing dumbbell press in terms of overall shoulder activation. And it also outperformed the seated variations. Therefore, it’s a viable alternative.

Nonetheless, the other variations are still effective exercises. You can cycle through the variations in your program as needed.

For example, if you plateau on the standing overhead press, feel free to switch over to the seated dumbbell press. You can also make this switch if you get bored of performing one exercise for several months. Regardless, I’d suggest sticking to one variation for an extended period of time before considering a swap.

Exercise 2 – Lateral raises (Emphasizes Lateral Deltoid)

This next exercise is commonly performed in the gym. It’s also one I highly recommend for lateral shoulder development. It’s going to target mainly the lateral deltoid with moderate involvement of the other two heads and the upper traps.

shoulder routine lateral raises

This exercise was shown in this study by Behren & Buskies to elicit the highest activation of the mid delt when compared to other common shoulder exercises.

However, given that this exercise is so popular, I want to go into more depth regarding proper form. And crucially, how to maximize shoulder activation while minimizing stress at the shoulder joint.

How To Perform Lateral Raises Properly

When you lift the weight to your side, the activation of each portion of the delt depends on the extent to which it’s in a direct line of the force opposing gravity.

So without any shoulder rotation, you can see that the lateral deltoid, as well as the anterior deltoid, are in a direct line of the force opposing gravity. Meaning they will both be sufficiently activated.

internal rotation dumbbell

To internally rotate your shoulder, think about as if you were pouring water from a pitcher. This then takes the anterior deltoid out of the equation. And makes the lateral deltoid in the most direct line of force which is the one we want to target.

shoulder exercise with internal rotation

 However, this is a dangerous position for the glenohumeral joint to be in. This will lead to wear and tear and shoulder impingement in the long run (which can take months or even several years to happen).

To fix this, what you want to do is externally rotate your shoulder when performing this exercise.

Gravity affecting weight

But you may notice the muscle in the direct line of force now is the front delt. So to address this and put more emphasis on the mid delt, you can do one of two options.

Lateral Raise Options

Option 1: Slightly lean forward so that the lateral deltoid is now more in the line of force.

Option 2: Perform the exercise on an incline bench which is the same idea.

incline bench option

But in both cases, you want to ensure that you’re slightly externally rotating the shoulder.

Exercise 3 – Reverse pec deck (Emphasizes Posterior Delt)

Now we are going to put more emphasis on the rear delts. As I mentioned earlier, their development is essential for balanced development of the shoulder and long term health. This exercise is going to mainly emphasize the posterior deltoid but will involve various other secondary muscles.

reverse pec deck

Studies like this one by Pinto and colleagues have shown that the reverse pec deck elicits higher rear delt activation than the seated row and lat pulldown. Meaning that including them in your routine is essential for optimal rear delt development.

But – which handle to use on the machine? This study from the Journal of Strength and Conditioning research showed that the neutral grip, where the palms face each other, elicited higher posterior delt and infraspinatus activation than the pronated grip where the shoulders are internally rotated and the palms face down. This indicates that the neutral grip might be the better option.

Why is this the case? Well, aside from horizontal abduction, the posterior deltoid also functions to externally rotate the shoulder. Since the neutral grip involves more external rotation than the pronated grip, it makes sense that it elicits higher rear delt activation.

The researchers also proposed that the pronated grip position places a considerable stretch on the posterior deltoid. Thus, this position may prevent it from developing adequate force due to the length tension relationship. But, this hypothesis requires further study.

Reverse pec deck Grip Variations

However, it’s important to note that there was a lot of variation in this study. Some subjects found the other grip more effective, so try out both and see which feels better for you!

Exercise 4 – Lying Face Pulls

This exercise is my personal favorite when it comes to really isolating the rear delts. And is something I highly recommend you try out. Although this variation will target similar muscles as the traditional standing face pulls will, it will lessen the involvement of the traps (more specifically the upper traps).

face pulls for shoulder development

This is because, as shown in this study from the Journal of Sports Medicine, the upper traps are more active during standing exercises since they work as a postural muscle.

Thus, laying on the ground:

  1. Eliminates the effects of gravity and
  2. Can decrease excessive activation of the upper traps

This is beneficial because most people tend to have overactive upper traps. Overactive upper traps tend to overpower the rear delts in many movements. So by performing this exercise lying down, it enables the rear delts to be more involved by lessening the involvement of the upper traps.

However, keep in mind that the traditional face pulls still have their benefits. They can help strengthen the rotator cuffs and postural muscles. So I’d strongly advise that you still incorporate them somewhere in your routine or do a few sets of each variation.

Shoulder Fiber Type

As for fiber type, the shoulders have been shown in numerous studies to be pretty much an even 50/50 split between type I and type II muscle fibers.

A common belief is that:

  • Type I fiber growth – Best stimulated by high reps with low weight
  • Type II fiber growth – Best stimulated by low reps with high weight

Some studies agree with this. However, others show that both fiber types will grow regardless of the rep range used.

But I think that research is still leaning towards including a varied rep range given their fiber type distribution. Thus, I think that both high reps and low reps in your workout would be the best option in terms of hypertrophy.

Sample Workout

So to wrap this all up, here’s a sample workout you can do using the exercises previously discussed. Feel free to swap or add exercises or split the workout in half if you’re training shoulders more than once a week.

Overhead press: 3-4 sets of 6-10 reps

Lateral Raises: 4 total sets (2 sets 6-10 reps, 2 sets 12-15 reps)

Reverse Pec Deck: 4 total sets (2 sets 6-10 reps, 2 sets 12-15 reps)

Lying Face Pulls: 2 sets of 8-12 reps

Standing or Kneeling Face Pulls: 2 sets of 8-12 reps

  1. Great video and workout. Just wrapped up today with adding these into my shoulder workout. Loved them. Keep up the great work.

  2. Hey Jeremy,

    Thanks! Finding you on youtube has done wonders for my workouts and development, and I’m 65 years old. One question, is it possible for you to recommend alternatives to the cable and machine sets that just use weights or suspension? I hate to have to skip an exercise in my home gym because I don’t have a pec-deck.

    Thanks again,
    –edge

    1. Thanks Jeremy! I’ve watches a lot of your videos, but haven’t seen a discussion on time between sets and reps, and how type I/II fibers react. Can you comment?

  3. Hi Jeremy
    You are doing a great job. I am one of the biggest followers of you.Can I use the same order for every week as you mentioned

    1. Jeremy Ethier

      Yes – try to “lean away” as you perform them by hanging onto a pole, as it decreases the involvement of the supraspinatus and increases involvement of the lateral deltoids.

  4. Hey JEREMY,
    You have such a great content! Really loved this article. You have demonstrated all the things properly. Can you tell me is doing Dumbbell Overhead Presses increases pressure on lumbar area lower back?

    1. Jeremy Ethier

      Thanks! There will be more tension in the lumbar area for that exercise but it’s not necessarily a bad thing unless you experience pain/discomfort, in which an alternative overhead exercise would be ideal.

  5. Derek Brouwer

    Hey Jeremy, keep up the great work, glad I found your YouTube channel, started with your complete upper and lower workouts three weeks ago, and it’s noticeable, time to start specific workoutouts now, having problems getting the PDF’s to send to my e-mail though?

  6. Hi,

    Do push ups (e.g. 40/day) sufficiently work the front and rear head of the deltoids (not for huge mass building) or do I need to do other isolation exercises for these?

    Thanks,
    APR

  7. Ahmad Abu Raddad

    Great videos, I watched the majority of your videos and have made better progress since, thank you very much.

    I subscribed to receive the PDF for this blog post but it was never sent from the server, please send it to me.

    Thank you.

  8. How do you incorporate these shoulders exercises with chest exercises and triceps exercises for a Push/pull legs workout?
    There are way too many to do in a single day if you do them all.

  9. Thanks for the information Jeremy. Im Always interested to know the science behind the various excercises…been watching your videos too.
    I’ve been incorporating face pulls in my routine now past few months …made significant shoulder gains after that.
    I hated shoulder workouts initially when I started lifting. More so after i injured my left shoulder while bench pressing…I realised it may have been caused by my negligence towards shoulders. Im learning proper form and better exercises.. I really like working on it now.
    I start off by warming up the rotator cuffs, by internal and external rotation of shoulders with light weight, it really helps.

  13. I was wondering which shoulder exercise is best for shoulder and i found your post on google. thanks for sharing such information and definitely i am gonna to take benefits from it.

  14. Mahmoud Hesham

    You are suggesting a 16 set workout , but you made a youtube video about 10 set limit for each muscle group , or did you mean for each head
