My bicep popped real loud 15 years ago. Guys on the other side of the gym were going "holy shit what was that loud pop?"...Im laying on the ground holding my arm, which was totally deformed by the rupture and has been deformed ever since. It was the bicep long head and thats a tendon we dont need . A surgeon told me that reattaching the tendon would be cosmetic only so I said screw it, leave my bicep deformed. The deformed bicep actually looks cool . It was an improvement.lol
