Stand with your feet hip-width apart. Hold dumbbells up at your shoulders—elbows bent and pointing out to the sides, palms facing forward. Take a giant step forward with your right leg and lower your body until your knees are bent 90 degrees. Your knees should be in line with your ankles. (A) Press into your right foot, straighten your right leg, and come to a stand, simultaneously pulling your left knee forward in front of your hips (so you’re standing on one leg) and pressing the weights up toward the ceiling .(B) Return to start. Repeat with your left leg.10 to 12 reps per leg
To make the move more challenging, place your front foot on a step.
