The magic circle helps sculpt, tone and condition your body.
The following exercises are from the book Pilates Evolution The 21st Century – by Joseph Pilates, Judd Robbins, and Lin Van Heuit-Robbins.
Stand relaxed, legs shoulder width apart, holding the circle at chest height. Place the palm of each hand on the outer pads of the circle, fingers extended. Inhale to begin. Exhale slowly to the count of four as you squeeze the circle, contracting your pectoral muscles.
Follow the first exercise with a mid to upper back balancing exercise. Remain standing and bring the circle around behind you, palms against the outer pads. Inhale to begin. Exhale slowly to a count of four, as you squeeze the circle, engaging your back muscles and drawing your shoulder blades inward simultaneously.
Use the same standing position as above. Place the circle against your right shoulder. Bring your palm above the top of pad and inhale to begin. As you exhale, push downwards toward the shoulder for a count of four. Inhale to relax, and repeat. After your repetitions, switch to the left shoulder.
Place the circle horizontally against your hip. Place your palm against the circle, fingers extended. Inhale to begin. Exhale to a count of four as you squeeze the circle inward against your body. Repeat, and then switch to the other side.
