Why do my bi's hurt while doing heavy bench presses?

[Slyder190]

Never had this problem until recently.

Co-activation, ususally only happens to newbs though

Tendonitis, I've had the same thing before. Since your upper back cant rotate because of the bench, it puts alot of stress on the biceps. Take a week or two off to recoup and start throwing in some hammer curls in your routine.

I wish I could figure it all out myself.

The past 3 weeks I haven't squatted heavy or been able to do heavy GM's...and the pain is gone.

What days are you squatting in correlation to your benching?
