5 Gym Mistakes That Can Tear Your Chest Tendon

Many gym-goers walk into a workout feeling normal and leave unable to lift their arm. The cause is often a torn pectoralis major tendon, an injury that happens suddenly and without any warning. Dr. Amr Elyamany lists the five mistakes that lead to it.
The five mistakes
- Lifting a weight heavier than you can control.
- Lowering the bar deeper than the normal bench range.
- Over-extending the arms while carrying the load.
- Skipping the warm-up before the workout.
- Ignoring severe pain in the shoulder or chest.
Why it happens
The pectoralis major tendon attaches your chest muscle to the upper arm bone. It is a strong tendon, but very heavy chest exercises, especially with poor control, can overload it until it tears.
How to protect yourself
- Reduce the weight and control every repetition.
- Warm up properly before any session.
- Stay within a safe depth on the bench press.
- Stop and get examined if a sudden sharp pain or a pop occurs.
Key takeaway: Lighter weight, controlled movement and a proper warm-up protect the tendon better than any supplement.
When to see a doctor
- A sudden pain or pop in the chest or shoulder while lifting
- Bruising or swelling on the chest or upper arm
- Weakness when pushing or difficulty lifting the arm
