Why your left arm got numb after doing pull ups?

Numbness in your left arm after doing pull-ups could be due to several factors, such as nerve compression or poor circulation. During pull-ups, the position of your body and the strain on your muscles may compress nerves in your shoulder or neck, leading to temporary numbness. Additionally, overexertion or muscle fatigue can contribute to this sensation. If the numbness persists or is accompanied by pain, it’s advisable to consult a healthcare professional.
