I was watching some cycling videos and I saw this one of Lance on the Alpe D'Huez and I noticed that the other riders were seated, some standing occassionally, even a teamate he was drafting off of was seated, but he never sat down. Every rider has their own style obviously but with his accomplishments he must be doing something right. Would there be benefits from standing and mashing the entire climb? I'm not trying to be like LA just wondering if there could be benefit from always climbing out of the saddle.
