yeah, i definately stopped the leg portion of my workouts a couple of months ago. like i said in my earlier posts, i am doing core and upper body because i really need to get them stronger, and biking doesnt' really help that at all. for leg strength, i do hills (only about 200ft max around here) sitting in a really big gear. there was an article in bicycling three or four months ago that gave several schedules. i have been following the time trialer one with a few modifications to assist in sprinting (see other thread). no leg weights. i was asking primarily because it seems as though same muscle group twice a day might be too stressful.
