Grab a heavy dumbbell and hold an end with each hand at arm’s length in front of your waist. Set your feet about twice your shoulder width apart, your toes turned out slightly. Lower your body as far as you can by pushing your hips back and bending your knees. Pause, then push yourself back to the starting position. Keep your torso as upright as you can for the entire movement, with your lower back naturally arched. Continue for one minute and then rest for one minute. Do for a total minutes.
