Peak Pilates Master Trainer Colleen Glenn shows Rolling like a Ball, an introductory exercise meant to stimulate the spine, deeply work the abdominals, and tune us into the inner flow of movement and breath in the body. During this demonstration, Colleen offers insight to common mistakes made during the exercise, as well as how to use your lower abdominals and biceps to complete the exercise. Rolling like a Ball transitions into Single Leg Stretch.
