Shoulder pain during running often stems from overuse, poor posture, or muscle imbalances. These issues strain the shoulder girdle, even though running primarily engages the legs.
Running is a full-body exercise, but improper form or excessive arm movement can overwork the shoulders. The rotator cuff and surrounding muscles stabilize the upper body during impact, leading to strain if overused.
The most common reasons for shoulder discomfort during runs include:
Many runners assume shoulder pain is normal, but it often results from avoidable habits. For example, clenching fists or swinging arms too high strains the shoulders unnecessarily. Proper form keeps arms bent at 90 degrees and close to the body.
I noticed my own shoulder pain improved after adjusting my arm swing and strengthening my core. A physical therapist confirmed that many runners overlook these adjustments until pain becomes severe.
Persistent shoulder pain during or after running may indicate a deeper issue, such as tendinitis or a rotator cuff injury. The American Academy of Orthopaedic Surgeons recommends seeing a doctor if pain lasts more than a few days or worsens.
Shoulder pain that doesn't improve with rest or form adjustments may require professional evaluation. Ignoring chronic pain can lead to long-term damage.
To avoid shoulder discomfort, focus on proper form, strength training, and recovery. Strengthening the upper back, shoulders, and core reduces strain during runs. Stretching before and after running also helps maintain flexibility.
If shoulder pain persists, consider seeing a physical therapist or sports medicine specialist. Addressing the root cause early prevents further injury and improves running performance.
