So I'm forcing myself to do weights. I compromised with myself that on the days I go spinning, I can get to the gym early or stay later and work on the upper body and inner/outer thigh weights. This only adds about 25 minutes to my workout, and it needs to get done.
My legs are very muscular and I DON'T want them to get any bigger, they're very toned and you can see the muscle definition. The question is, is it ABSOLUTELY necessary to do weight lifting on my legs? I know if you have more muscle, you burn more calories, but I feel like they get a pretty good work out from all the cardio I do (that has a lot of resistance on it most of the time).
