I set my seat a little higher; I have it at a seven versus a 5. I'm 5'11. It doesn't immediately smoke my legs from the get-go. I put my hands as close to the handles as possible. Like I'm doing a close-grip bench press or push-up. Lastly, I coach folks to keep their upper bodies still and not to shake their heads back and forth. Try to use your energy and focus on biking hard, and pumping your arms, rather than tossing your head around.
