Though I've been a reader here for a while, I haven't been very active. My wife and I are starting to work out more, and currently we are using what equipment we have been given to start with. My question is for her though, it's about building muscle in the legs/hips/thighs. She wants to tone in that area, and get a slimming effect. One of our friends, who works out constantly, said she should not work her legs at all except aerobic exercises. So far we've been doing arms, shoulders, chest, back on a bowflex (it was free and I don't have any free weights yet.) Then on odd days we do some sort of cardio/aerobic exercise. Then comes the question: Should she do weight training on her legs etc, or should we continue the current routine? Secondly, if we are only working upper body, will we be in danger of over training by doing it Monday, Wednesday and Friday?
