Shoulder pain while doing push ups is a common complaint that often points to a movement dysfunction rather than a simple lack of strength. This discomfort typically signals that the load of the exercise is not being distributed evenly through the joint, placing abnormal stress on the soft tissues. Understanding the mechanics behind this pain is the first step toward correcting form and preventing more serious injuries.
Identifying the Source of Discomfort
To address the issue effectively, you must first determine where the pain is located and when it occurs. Pain isolated to the front of the shoulder often involves the rotator cuff tendons or the bursa, while sharp pain on the side of the joint may indicate impingement. Recognizing the specific trigger—such as the descent phase or the push-off—helps narrow down the root cause of the problem.
Common Mechanical Causes
Elbows flaring out to the sides, which narrows the subacromial space.
Insufficient scapular stabilization, leading to winging or shifting.
Limited thoracic mobility, forcing the shoulders to compensate.
Overuse or inflammation of the rotator cuff muscles.
How Form Influences Joint Health
The position of your body during a push up dictates how the force travels through your shoulders. When the hands are placed too wide, the angle of the humerus changes, pinching the tendons against the acromion. Conversely, placing the hands too close can overload the front of the joint, creating friction and pain.
Optimal Alignment for Safety
Maintaining a straight line from head to heels requires active engagement of the core and glutes. Your hands should be positioned roughly under the shoulders, with elbows tucking at a 45-degree angle to the torso. This alignment allows the larger muscle groups to share the workload, reducing the burden on the vulnerable shoulder structures.
Many individuals unknowingly shift their weight forward onto their hands, which destabilizes the shoulder girdle. This forward lean often results in the shoulders hiking up toward the ears, a position that compresses the joint. By focusing on keeping the shoulders down and back, you create space in the joint and allow for a smoother range of motion.
Progression and Regression Strategies
Adjusting the difficulty of the exercise can immediately relieve pressure on the shoulders. If standard push ups cause pain, switching to an incline push up using a bench or wall reduces the load significantly. This regression allows you to build strength in a safer angle while correcting your form.
Recovery and Preventative Measures
Rest is crucial if the shoulder is inflamed, but complete immobilization is not the solution. Gentle mobility work, such as cat-cow stretches and thread-the-needle exercises, can restore the natural movement of the thoracic spine. Strengthening the serratus anterior and lower trapezius helps stabilize the scapula, creating a solid foundation for pressing movements.
