Don't overdo the cardio - 10 weight loss rules - Women's Health & Fitness

8. Don’t overdo the cardio

If you want to lower your body fat and gain lean muscle, too much cardio is counter-productive – especially the popular long, slow kind such as long-distance running or cycling. Muscle wastage occurs when performing a lot of long-duration cardio, so instead try two to three short, high-intensity sessions and only add longer, more moderate sessions as a last resort. The aim should always be to do as little cardio as possible if body recomposition is your goal.
