Your biceps do far more than simply bend your elbow. During climbing, they play an important role in pulling, locking off, stabilising the shoulder and controlling movement during dynamic sequences. Over time, repetitive loading can irritate the muscle, tendon or surrounding structures, particularly if training volume increases too quickly or your shoulder isn’t moving efficiently.
Climbing bicep pain often develops gradually rather than after one specific incident, although it can also occur following a powerful move, an awkward catch or an unexpected fall.
Pain is often felt at the front of the shoulder, down the front of the upper arm or around the crease of the elbow. Some climbers notice discomfort during lock-offs, underclings, gastons or while lowering from routes.
Without addressing the underlying cause, symptoms often continue to return every time climbing intensity increases.
