Clutch question: knee or ankle?

I have no idea, and now I'm going to think about it on the way home and I'll probably end up killing it.

Reminds me of a great trick on the golf course: if you have money on a game (or you just want to mess with the other golfer) ask him after his practice swing, but before his shot, do you breathe in or out on your backswing?

Nobody else uses their hip? I let my hip do most of the work and use my knee and ankle for fine adjustments.

Yeah, I'm a hip guy, too. Generally because my big feet don't have room to flap around in the foot box, so my leg has to follow the swing of the pedal.
