Dear @hungryginger, i don't know much like you. As I am your fan I want to share this dear "Lie on the floor with arms extended perpendicular to the torso and lower calves and heels resting on the ball. Engaging the glutes and abs, lift the hips up from the floor. Use your outstretched arms for stability—you'll feel wobbly! "
Thanks for your sharing dear. Have a good day.
