I did a seated low cadence climbing ride today. I found myself on the tops and the hoods but my hip angle (bent over position) was always the same. I have been working hard this season to improve my climbing technique which is firing the glutes and keeping my feet in the tops of my shoes de-emphasizing the quads. The glutes are the largest and strongest muscle and get a good blood supply versus the quads which fatigue more easily. I keep a very light touch (very little weight) on the handlebars and steer the bike with my core as if riding no hands.
