Why does my elbow hurt during workouts?

THERE ARE MANY conditions that can affect the elbow, but the most common is lateral epicondylitis, or “tennis elbow”. This condition is a process called tendinosis, or a degeneration of the tissue, not to be confused with tendinitis—an inflammation.

Cells called fibroblasts form collagen, but due to repetitive stress on the tendons, the collagen is formed irregularly and reduces the strength of the muscle, which leads to constant injury and, eventually, tearing. Each time the collagen is torn, scar tissue is formed in the tendon, further weakening it.

Performing the same routines in the gym, neglecting to train every muscle group, and lifting excessively heavy weights are the most common causes of elbow pain, all of which create muscular imbalances and increase the strain on the joint.
