When the tendons that attach the Pectoralis Major Muscle (the large muscle in front of the chest way) to the arm bone tear completely, athletes report a Pectoralis Rupture. These injuries which are far more common in men than in women, can potentially happen to any athlete who engages in weight training. Working out, particularly with a bench press can cause these tendons to tear. However, they can also be torn as a result of high contact sports such as soccer, rugby, hockey, etc. While a “pec tear” may heal without surgery, a complete “pec rupture” of the tendon will likely require surgery to reattach the tendon to the bone.
