Serratus punch
From Wikipedia, the free encyclopedia
The serratus punch is an exercise that works scapular protraction using the serratus anterior muscle and to a lesser extent the pectoralis minor.[1][2] The exercise even performed at maximum voluntary isometric contraction did not increase pain in one study in people with shoulder pain.[3] Because strengthening the serratus anterior improves shoulder stability, the exercise is recommended for people suffering from shoulder pain or bad posture[4] and is recommended in one treatment protocol as non-surgical treatment for a rotator cuff tear.[5]
