OK, I may be out of line here but coming from weight lifting and just now getting into cycling, I've learned from my weight lifting days that its the proteins that helps rebuild muscle tissue and really helps the musles from aching after extreme/extrenous exercises. I have tried just using endurox before but still found myself hurting the next day. But once I've resumed taking protein drinks again, %100 Whey, along with endurox I've noticed that there was considerably much less pain after my bike rides.

Am I wrong here? I don't see too many people in these forums talking about protein that much.
