Can a person with cubitus valgus perform pull-ups on a horizontal bar?

Generally speaking, cubitus valgus refers to outward angulation of the elbow joint. Whether a person with cubitus valgus can perform a pull-up depends on their upper limb strength. If sufficient upper limb strength is present, they are usually able to complete the movement; if upper limb strength is inadequate, they may not be able to do so. If discomfort occurs, medical advice should be sought promptly. The detailed analysis is as follows:

Cubitus valgus itself does not directly determine whether a person can perform a pull-up; the key factor lies in the strength of their upper limbs. Upper limb strength—particularly the muscles of the arms, shoulders, and back—is crucial for performing actions such as pull-ups. When an individual has sufficient upper limb strength, they can contract these muscle groups effectively to overcome their body weight and successfully pull themselves up to the bar. Therefore, even with cubitus valgus, performing a pull-up is generally feasible as long as adequate upper limb strength is present.

If an individual lacks sufficient upper limb strength, they may be unable to perform a pull-up regardless of whether they have cubitus valgus. Insufficient upper limb strength limits the ability of the muscle groups to contract effectively, making it impossible to generate enough pulling force to lift the body. In such cases, even without cubitus valgus, performing a pull-up would still be extremely difficult or impossible.

Individuals with cubitus valgus who experience pain or discomfort while attempting pull-ups should stop immediately. Continuing to force the movement may exacerbate elbow joint damage and potentially lead to more serious complications.
