I've always lifted on and off so I have a basic idea of what my arms are supposed to feel like the day after a workout. I did bi's yesterday and thought it was a pretty good workout, got a great arm pump, worked the muscle to exhaustion, etc, but today I don't feel anything. No soreness or pain or anything. It used to feel like I wouldn't be able to bend my arm for a day or two. I've been upping my protein, and taking creatine/glutamine pills, but I don't think that would change much. Did I do something wrong?
