Strength-train for more weight loss

Strength training is the secret weapon you need if you want to break the plateau and lose the pounds. Adding resistance builds muscle and helps you burn more calories during (and after!) your workout, notes Tom Holland, author of Beat the Gym. In fact, researchers found that women who did strength training increased their resting metabolic rate (the calories your body needs to get through the day) for as long as 16 hours post-exercise.

So add some weights to your workouts, that will allow you to do 10 reps of each move, going from one exercise to the next with no rest, then take a one-minute break. Do three circuits total.

Follow this metabolism-revving, total-body routine two or three times a week.
