Thread: how to do i lose weight fast without gaining muscle?

i did track last year and got really large muscular thighs and i can't get rid of them. i tried just sitting around and not using them but now i've gained a little more weight from fat. i'm scared that if i work out i'll just get bigger muscles. are there exercises that burn lots a calories while lengthening muscles instead of growing them?

overdoing cardio can burn muscle. walking instead of running can make you lose weight and not gain you too much muscle. i guess you would stay away from weight lifting?
