Working with light dumbbells can be quite effective if you perform the moves with correct technique and alignment. In this exercise, maintain a straight spine throughout the move for maximum benefit.
Grasp a 3- to 5-pound dummbell in each hand and stand with your feet hip-width apart, toes facing forward. Bend your knees and sit back on your heels to avoid putting stress on your lower back. Begin with your elbows bent and tucked in to the sides of your body, palms facing forward.
