I do not need to lose weight because I am 5’4 and 109. I want to have a totally hard body though. I want abs, nice arms, and a firm but and legs. I need some advice. Currently, I run/walk, spinning, tai chi, crunches, and curl 15 lb dumbells. Will I see results from this? What else can I do? Since I am already thin how long til I see results?
