Works: lower body and endurance
Stand up straight while keeping your head in line with your spine. Place your left hand on your hip and hold a dumbbell in your right hand. Balance on your left leg and bend forward at the hips lifting your right foot off the floor and extending that leg behind you. Continue bending at the hip until your torso is horizontal to the floor, letting your right arm hang straight down from your right shoulder. Return to your starting position.
Perform 3 sets of 10 reps on each side.
