1. Anyone have the animation that was a leg on a crank doing the pedal stroke listing each muscle that was used in each part of the stroke?
2. Also on a side note, I always see it mentioned that people who ride A LOT develop like 3 out of 4 of the leg muscles and one of them doesnt get "worked out" which leads to a tightness or something like that. Anyone know what muscle is the one that gets left out on a bike?
