For anyone wanting to tone up or lose body fat THIS IS FOR YOU! Working out burns more calories over-all then cardio because it burns calories for over 24 hours rebuilding the torn muscle fibers. Cardio keeps you burning calories for only about an hour or two after you're done.
THE ANSWER: Do both!! Both males and females should do cardio AND work out for most efficiency in toning or losing fat. Simply having more muscle on your body burns fat!! Noo, ladies you won't "bulk up" if you lift weights!
