One of the strong points about my physique has always been my biceps, but unfortunately last week I injured my right one.
Last Friday, I was doing single arm preacher curls with 75lb (34 kg) dumbbells (nothing new for me, have been doing this weight for months). I guess my form was a little off and I felt a really sharp pain in my bicep on the second rep, I dropped the weight immediately.
The pain was not at the shoulder or at the elbow, but in the middle of my bicep.
It hurt to flex or extend my arm, so I left the gym immediately. The second day, I could extend my arm but it hurt to flex. Fast forward a few days and all pain is gone. I re-entered the gym on Monday and did exercises without a pulling motion. Today, I worked back and I was fine for most of the workout, until I attempted a heavy deadlift set (I know, stupid). My bicep is hurting a little when I flex, but not as bad as the original pain.
Obviously I need to rest it more, this just seems like a Grade 1 sprain, and I think I'm going to take the whole week off next week (I haven't taken a break in over a year, it's probably long needed).
My question is, is this just a sprain? And will my bicep now be susceptible to injury/tear more often? Or will it heal back 100% after sufficient rest?
