I’m 5’9″ 160lbs 32″ waist I don’t eat junk food, but I don’t exercise either. My goal is to replace the fat I have with muscle, but still be thin… to have that basketball player look. I’ve started weight training, but about to begin cardio… How many minutes/hours of treadmill work should I do per day?

Tired of the same ol’ treadmill workout? Try something new. Sarah D walks you through a treadmill interval workout
