Quantity vs. Quality

It's tempting to push for quantity over quality. It may seem as if doing more sets or exercises could give you better results ― and faster. Wrong! Even if you do your exercises with perfect form, you can still overdo it by pushing too much in a single exercise session. If you want to maximize your results (and who doesn't?), try splitting your workouts into two sessions. Do cardio training (such as running on the treadmill) in the morning, for example, and then do resistance training in the evening. The basic concept is that multiple daily training sessions produce afterburn. In simple terms, this means you burn calories not only during exercise but afterward. Up to 25 percent more calories can be burned hours after you train, which elevates your basal metabolic rate, or BMR. By splitting your workouts, you'll reap the benefits of twice-a-day afterburn without overtraining your muscles.
