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?

rounded shoulders 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.

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.

  1. 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
