With your knees slightly bent, lean forward at about 45 degrees, keeping a flat back. Holding a dumbbell in each hand, extend your arms below your shoulders.
Draw your elbows back, lifting the dumbbells up to chest level, squeezing your shoulder blades together as you do. Be sure to keep your elbows in and pointed upward. Don't arch your back.
Slowly lower the weights back to the starting position.
