This blog post contains 7 of the best ways to perform a Serratus Anterior stretch.
Start here:
Serratus Anterior Release
Before stretching the Serratus Anterior, it is recommended to release this tight muscle first.
Instructions
- Lie down on your side.
- (The side that will be stretched will be the one that is closest to the floor.)
- Place a foam roller underneath the Serratus Anterior muscle.
- Apply an appropriate amount of your body weight on top of the foam roller.
- Roll your body over the foam roller.
- Make sure to cover the entire muscle.
- Continue for 2 minutes on each side.
How to Stretch the Serratus Anterior
Note: It can be quite difficult to feel a stretch in the Serratus Anterior. Make sure that you try ALL of the different stretches as suggested below to see which one is the most effective for you.
1. Stretch in Side Lie
(This is my personal favorite Serratus Anterior stretch!)

- Keep your shoulder completely relaxed.
- Bow your torso towards the floor.

- Aim to feel a stretch on the side of your ribs.
- Hold this position for 30 seconds.
2. Floor Stretch
Instructions:
- Lie down on your stomach.

7. Eccentric Strengthening Exercise
(This exercise will strengthen the Serratus Anterior muscle as it is lengthening.)
Instructions:
- Lie down on your side.
- (The upper side will be targeted.)
- Hold onto an appropriate amount of weight.
- Straighten your arm so that it is perpendicular to the floor.
- Keep this arm straightened throughout this exercise.

- The movement should be coming from the scapula gliding back onto the rib cage.
- Perform 20 repetitions.
Any Questions?
Do you have any other questions that you would like to ask me? Feel free to leave me a question in the comment section.
a) What causes a tight Serratus Anterior?
One of the main causes of a tight Serratus Anterior is having the Rounded Shoulders posture.
When your shoulders slouch forwards, the shoulder blade protracts forwards along the rib cage.
This places the Serratus Anterior muscle in a chronically shortened position.
Over time – this can lead to tightness in the Serratus Anterior.
b) What does a tight Serratus Anterior feel like?
One may experience tightness and/or pain at the sides of the rib cage.
It can also lead to difficulties moving the shoulder above shoulder height.
c) Can the Serratus Anterior cause rib pain?
As the Serratus Anterior attaches directly onto the ribs 1-9, any issue in this muscle can refer pain into the side of the rib cage.
Serratus Anterior Weakness and Winged Scapula

The Serratus Anterior is the primary muscle that anchors the scapula flat onto the rib cage.
If there is weakness and/or poor control of the Serratus Anterior muscle, this can lead to a Winged Scapula.
This is where the medial border of the shoulder blades protrudes off the rib cage.
If you experiencing this scapular winging, it is likely that you will need to learn how to activate and strengthen your Serratus Anterior.

Conclusion
If you have tightness and/or pain around the sides of the rib cage, this may suggest that you have a tight Serratus Anterior.
Try out the Serratus Anterior stretches as suggested on this blog post to help relax this muscle.
Remember – it can be quite difficult to stretch this muscle. Try to position your body to the best of your ability to achieve the desired stretch.

Hi Mark,
thanks for the serratus anterior stretch nr. 1 on your website!
I like it a lot, and started modifying it by placing my hips a bit higher,
on the edge of a couch/bed, in order to create more downward (footward) stretch on the serratus. If you have any advice on that, please let me know, thanks!
(Feel free to include this variant on your website if you like.)
Best wishes and keep up your good work! Max from Berlin
Hey Max from Berlin,
I do this stretch on the edge of a couch too! It really hits the spot.
