i'm a very dedicated racer, and i don't touch the weights. i used to be a musclebound freak before i started cycling. 2 hours a day, 5 days a week, creatine, high calorie shakes, etc. it's been about 3 years since i left the weights alone, and i'm only now considering doing push-ups...just because. definitely no leg work, though. i'd rather put that effort on the bike.
