serratus anterior exercises for healthy shoulders

Shoulders are critical joints, but most people don’t know much about how to keep them healthy.

Strengthening with serratus anterior exercises will keep your shoulders mobile and strong, helping you avoid injury and live your active life.

You may not know if you’ve got a weak serratus anterior. Hell – there’s a chance you may not even know what a serratus anterior is (we’ll get into that in a minute).

But I bet you have an idea of how strong your shoulders are.

You know how hard you can throw a punch, your max on military press, or how strong and stable your shoulders feel during push-ups…

If those shoulders have been feeling a little more on the weak side lately, your serratus anterior might be the key.

This is especially true if you’ve noticed that your scapulae seem particularly visible.

Maybe you’ve caught a glimpse in the mirror after hopping out of the shower and did a double take, thinking, “Have my shoulder blades always looked like that? …Almost like little wings?”

This is called scapular winging and, you guessed it – the serratus anterior is involved, as is the health of your shoulder as a whole.

What is the Serratus Anterior?

The serratus anterior is most recognized by its serrated-looking appearance along the side of your body.

Depending on your body type and how shredded (or not) you are, it may or may not be visible.

Or, like this dude here, it may become visible during certain movements…

Although I’d prefer if those movements were more about serratus anterior exercises and not so much about opening up jars of food…

But regardless, these serrated points show the insertion point of the muscle on the ribs.

Your serratus anterior typically attaches to your first 8 ribs [1], but it lies deep to your pectoral muscles, so you won’t be able to see all of these “serrations” – even on a super lean body.


From the ribs, your serratus anterior wraps around your side and back, where it runs underneath the scapulae and attaches there, to the underside of your shoulder blades [2].

What Does the Serratus Anterior Do?

Your serratus anterior plays a crucial role in how you move your shoulder and arm.

It works to protract your scaps (wrapping forward around your ribcage) which controls forward pushing movements of your arms [3].

This muscle also works with the lower and upper trapezius to rotate the scapulae upwards during shoulder flexion.

But perhaps one of the most important functions of the serratus anterior is to posteriorly tilt the scapulae.

Posterior tilt of the scapulae is important for healthy shoulders because it helps maintain the subacromial space.

The subacromial space is between the acromion process and head of the humerus. (Read more about how to prevent subacromial impingement issues in this article.)

Without sufficient room here, any movement that has your arms at shoulder level or above may cause shoulder impingement and result in an irritated bursa or rotator cuff tendon.

Thus, your serratus anterior provides a great deal of stability for your shoulder joint [4].

Because your serratus anterior helps forward arm movements and provides a few more inches of reach to your punches, the muscle is sometimes called the boxer’s muscle.

I remember teaching the function of the serratus anterior to a boxer I was training.

I was showing him the basic Scapular Pushup exercise that you’ll learn below and he asked why not just train the regular Pushup.

I told him it’s because we want to isolate the serratus anterior so I could see how it was functioning.

“What’s the point?” he asked.

I asked him to get in his fight stance as I said, “Here’s how training your serratus is going to help you.”

“Pretend you’re hitting me with your jab,” I continued as I let him put his fist on my chin.

Then I stepped back from his fist a couple of inches.

“Now, protract your scapula,” I instructed and as he did as I asked, his fist again met my chin.

“This is one way training your serratus is going to help. It’s also going to help keep your shoulders healthy and there’s nothing worse for your training than a shoulder injury!”

Serratus Anterior Dysfunction

Weakness in your serratus anterior can contribute to improper positioning of the scapulae, called scapular dyskinesis. This can happen in a couple of different ways.

The scapulae may start to tilt forward if that serratus anterior weakness is paired with tight pecs and a tight deltoid.

If the weakness is paired instead with additional weakness in the lower traps, the medial border of the scapula starts to flare up, or protrude – called scapular winging.

When this happens, you can sometimes visibly see that medial border of the scapulae protruding up from the back, like wings.

Sometimes winging might not cause any symptoms [5], and sometimes it can cause pain or weakness. But regardless, scapular winging is a clear sign that there are issues in the shoulder joint that need to be addressed with winged scapula exercises.

And as I mentioned above, serratus anterior weakness can also contribute to shoulder impingement [6].

By failing to properly control the scapulae, the amount of space in the shoulder joint itself can be reduced, leading to the “catching” of muscles and ligaments that characterize impingement.

5 Serratus Anterior Exercises

These 5 serratus anterior exercises all train the muscle in a different way so it can perform all of its functions effectively and keep your shoulders healthy.

Every muscle in our body does more than just its strict anatomical action, so whenever we want to target a muscle, we need multiple exercises to do it completely.

Otherwise, it’s kind of like letting your car get really dirty, then washing only one side of it.

There’s no point in making ONLY the driver’s side of your ride look super fresh!

Similarly, we don’t want to strengthen a muscle in just one area or for just one function – we want to build strength comprehensively for all of its functions, which is how to maximize movement longevity.

Scap Pushup

This exercise trains serratus anterior control exclusively during strict protraction and retraction.

Wall Scapular Pushup
Wall Scapular Pushup - serratus anterior exercises

  • Place your hands on a wall at shoulder height, tucking your chin slightly
  • Widen your rib cage as you protract the scapulae – your body should move away from the wall
  • Hold for 1-2 seconds
  • Retract the scapulae, moving your body slightly toward the wall and hold for 1-2 seconds
  • Move slowly and maintain control throughout the range of movement, moving only at the scapulae
  • Complete 12 reps

4 Point Scapular Pushup

  • Come into a quadruped position on the ground
  • Tuck the chin and start with a neutral spine
  • Keep the elbows locked as you retract the scapulae and hold for 1-2 seconds
  • Protract the scapulae and hold
  • Complete 12 reps

Scapular Pushup on Toes

  • Come into a regular pushup position on your toes
  • Slowly go through the full range of motion with control as you maintain straight elbows
  • Retract scapulae and hold, then protract and hold
  • Complete 12 reps

Supine Serratus Activator

This activator develops awareness of posterior tilt, then helps you train it.

  • Using a lacrosse ball, face a wall with one hand behind your back
  • Place the ball between the wall and the front of your shoulder
  • Drive your body into the wall, rolling over the ball for about a minute
  • Next, lay supine
  • Let your upper arms relax down and bend your elbows, pointing fingers up toward ceiling
  • Drive your elbows into the ground at about 50% power
  • Maintaining this action, open your chest, posteriorly tilting the scapula
  • Hold for 5 seconds, then release, completing 10 reps

Scap Step-up

Use this move to train asymmetrical scapular motion – one scap will be protracting while the other is retracting.

  • Find a step or something level 3-4 inches off the ground and come to a push-up position with your hands on the step
  • Take your feet slightly wider than a normal push-up stance and keep your elbows straight
  • Keep both elbows straight as you retract your scapula and slowly lower one arm off the step and onto the ground
  • Protract your scapula to bring that arm back up to the step with control and repeat on the other side

Horizontal Band Fly

This drill will build scapular protraction during horizontal adduction.

  • Grab a resistance band with both hands
  • Loop the band up and over your head so that the strap is lying across your upper back
  • Extend both arms out to the sides, keeping arms slightly below shoulder level
  • Keeping arms extended, bring them in so they’re reaching straight out in front
  • Protract the scapulae to drive the band forward slightly
  • Hold for 3 seconds, then adduct arms back out to side
  • Retract your scapulae and hold at the end of the range of motion for 3 seconds

Overhead Wall Rollout

Use this rollout to focus on upward rotation of the scap during shoulder flexion.

  • Grab an ab wheel and stand facing a wall
  • Outstretching your arms, place wheel on wall and step back a few inches so that you’re leaning forward into the wall
  • Protract the scapulae slightly to activate your serratus anterior
  • Slowly roll up the wall, shrugging your shoulders to elevate your scaps as you do
  • Go as far up as you can, then roll back down with control
  • Keep your core active and breathe throughout the motion
  • Complete 8-12 reps

These serratus anterior exercises will strengthen an important muscle, improve the health and stability of your shoulders, and help you recover from or prevent issues like scapular winging.
