Performing Back Extensions Come back up by extending your spine to complete the rep. Complete one to two sets of 12 reps. For the back extension hold, hold your body in the top position so that your torso is right in line with your thighs. Hold this position for two sets, with each one lasting 15 to 20 seconds.
Why Work Out Your Back Strength training your back muscles will add muscle mass to your upper body, which can help make your waist look smaller. Like your chest, your back is made up of big muscles that can handle heavyweight and, therefore, help you burn more calories.
