A change is not only as good as a rest, it has weight-loss benefits, too. “For the fastest fat-burning results, alternate between a week of high reps (12-20) and a week of low reps (6-10),” says personal trainer Dave Porter. Sticking to high reps robs your body of a constant challenge. “Muscles can grow content and plateau, and doing low reps burns more energy after the gym.” The new challenge will keep you shifting more kilojoules with each workout.
