You’ve been training for months, and now you’re ready! Ready to hit that huge bench press PR (personal record) that you know is coming. Your buddies are cheering you on, you are feeling amped, you know you’ll complete the lift, and….pop! A sudden searing pain goes through the front part of your shoulder. Oh no!

What you’ve likely experienced is a pectoralis (pec) strain. In this article, we discuss pectoral anatomy and function, treatment options, and rehab exercises for pec strains. We want you to get back to hitting those PRs in no time!

 

 

Pec Anatomy & Function

The pectoralis (pec) muscle is comprised of two muscles, the pec major and the pec minor. The pec major is a fan-shaped muscle that is located superficially (closer to the surface), and has two heads of muscle – the sternal head and the clavicular head. The main actions of the pec major are adduction (pulling the arm toward the body), internal rotation (rotation toward the body), and flexion (elevating) of the arm. Some of the movements that the pec major is responsible for are push up, bench press, and pushing or sliding an object forward.

The other pec muscle is called the pectoralis minor. The pec minor is located under the pec major (deeper toward the chest), and is mainly responsible for movements of the scapula (shoulder blade). Some of the movements that pec minor assists with are scapular stabilization when needed as well as muscular assistance with deep breathing. Tightening of the pec minor can cause significantly rounded shoulders and bent/slumped posture.

When & How Do Pec Strains Occur?

 

The majority of pec strains occur when the pec is placed under maximal tension or pressure, or put into a position that compromises the muscle’s ability to produce enough protective force to prevent injury.

 

LISTEN: WHAT IS THE BEST WAY TO TREAT A MUSCLE STRAIN?

Most commonly, injury occurs in the pectoralis major due to too much extension or external rotation for the tissue to handle, and most of these injuries occur at the musculotendinous junction (where the muscle meets the tendon) as this is a vulnerable area when placed under tension and stress (1). Most often, pec strains occur in situations such as a bench press or a sports-related trauma injury. (2)

 

When the pec is strained, it can feel like:

  • Acute pain
  • Swelling in the front of the shoulder
  • Bruising
  • Tissue deformity
  • Weakness, particularly in adduction and internal rotation of the arm
  • Possible numbness and tingling in the affected arm

The pec major can be injured at any portion of the muscle, including the thorax, sternal and clavicular attachments. Treatment will largely depend on the extent of the injury. 

 

Should I Get Surgery for a Pec Strain or Tear?

After an injury, it can be difficult to decide on the best course of treatment action. For pec strains, it will largely depend on the symptoms, extent of damage, and activity level of the person injured to determine the treatment plan. If the damage to the pec was extensive and the tendon or muscle belly was fully ruptured, a surgical approach will likely be recommended.

For a partial tear or strain, conservative treatment such as medications, manual therapies, and physical therapy will be the most effective treatment. In an article by Bayer et al in 2017, conservative treatment such as PT that happens early and often is BEST for optimal outcomes! (3) It has been shown that waiting to start rehab will ultimately result in less than optimal recovery and pain control after a pec strain. 

This notion appears to remain consistent for the athlete population according to research, the group in which pec strains occur most frequently. In an article by Sahota et al in 2020, a cohort of football players with pec strains were shown to have increased recovery times when a delayed surgical approach was taken, versus a non-operative, conservative approach with rehab and PT (4). Similarly for baseball players and most specifically, pitchers, a study done in 2022 looked at 138 people with pec strains. The vast majority of these players were treated conservatively and experienced similar, if not better, outcomes than those who underwent surgical treatment (5).

Get started now! Our 8-week Shoulder Rehab program is just what you need to get after that early rehab and take the guess work out of managing and rehabbing your pec strain! Get started today with a free 7-day trial! 

 

The moral of the story – treatment that occurs EARLY and OFTEN is BEST! Don’t wait!!

 

Exercises for Pec Strains

Since optimal treatment protocols typically start early when the injury is acute, rehab can be broken up into phases. These are most often classified as early, middle, and late stages of treatment. Below we will go through some exercises for pec strains.

 

Early Rehab Exercises for Pec Strains:

The goal for the early phase of rehabilitation is light activation of the injured area, as well as building up the scapular stabilizers that surround the pec itself. We want to be relatively gentle with our rehab in this phase and take our time with progressing.

 

Middle Phase Rehab Exercises for Pec Strains:

During the middle phase of rehab, we can challenge the pectoralis muscle a little more, with attention to stimulus for growth and repair.

The push-up is a great exercise to introduce in this phase. Beginning with a wall push-up can serve as a reintroduction into this movement and can be progressed to an eccentric push-up, focusing on the lowering phase to further challenge the pectoral muscle fibers.

 

Late Phase Rehab Exercises for Pec Strains:

In late-phase rehab, we are focused on really building and strengthening that pec, and getting back to safely increasing weight and load on the muscle.

 

Closing Thoughts:

Takeaways and learning points from this article are the following:

  1. Rehab should occur early and often! Full ruptures will likely require a surgical approach, but the vast majority of pec strains can be managed with a conservative approach such as PT with a multiphase treatment plan with specific exercises for pec strains.
  2. Listen to your body! Pain should not exceed 4/10 at any time you are exercising and rehabbing.
  3. Rehab does not stop when your pain is gone! Continue to build capacity safely and slowly over time with a monitored rehab program.
  4. With a pec strain there is a higher risk of restrain, so again, we should continue to rehab progressively over time.
