Exercise Advice: Take a little less than shoulder width stance and hold a kettlebell in one hand. Position the kettlebell at shoulder level with your elbow tucked into your side. This exercise is basically a reverse lunge so instead of lunging forward, you will be going backward with your lead leg. Slowly step back with your lead leg while extending your arm and pressing the kettlebell up over your head. Slowly lower the kettlebell down while stepping back to the starting position and repeat.
