Start lying on your back with a dumbbell in your right hand and your right arm extended straight above your right shoulder. Your right knee should be bent, with your right foot flat on the floor. Your left leg should be straight.
With control, roll your body up, keeping your left hand on the ground, until you're in a seated position. Be sure to keep the dumbbell directly overhead and in line with your shoulder.
Press your right foot into the ground as you lift both hips up off the ground and reach the dumbbell up toward the ceiling. Your left hand will act as an anchor during this exercise.
With control, slowly roll back down to the starting position. This completes one rep.
