Stand with feet hip-width apart holding a dumbbell in each hand. Hinge forward at your hips with your knees bent, holding the dumbbells, with straight arms, just in front of your legs. This is your starting position.
Lift the dumbbells straight up to chest level, squeezing your shoulder blades together as you do. Be sure to keep your elbows in and pointed upward, and try not to arch your back.
Slowly lower the weights back to the starting position to complete one rep.
