Begin seated on the ball. Walk your feet out while lying back until your mid-upper back is on the ball while your feet are flat, knees bent. Without moving legs, roll the ball forward so that your hips and butt drop toward the floor.
EXHALE: Using your glutes to pull you, roll the ball back as your hips rise up until your torso is in a straight line, parallel to the floor.
INHALE: Slowly lower down to start to complete one rep.
Make sure legs and feet stay stationary.
Muscles Worked: Glutes, Hamstrings
