many who are apply to ortho think to much like Cobra Kai
and you need to think more like Mr. Miyagi
having strength is only part of ortho. practicing orthopaedics is not holding a leg for hours. are there things that require some physical strength, sure. can people learn leverage techniques, most definitely. beyond the physical strength, stamina tends to be more beneficial than strength. even more important than physical stamina is mental stamina. most cases will not physically fatigue you, but they will mentally fatigue you. if you are going to train for the demands of surgery, concentrate on your physical stamina, more so than strength. hand and forearm strength is probably helpful as well. you really can't train for mental stamina required in a long case 5+hrs.
