First, place the noodle around your back, under your arms. Noodle ends should be pointing sideways. Lay on the back and rest your hands on the noodle. Keep both your legs straight, slightly below parallel and your toes pointed.
Move your legs together in small circular motion, with each leg forming a separate circle. First clockwise and then in the opposite direction. Slightly lift your torso as your legs raise.
Feel your lower abdominal as you raise your legs up and your upper abdominal as you raise your torso. Those will be your primary targeted muscles. Feel your lower back muscles as well as you push your legs down.
Inhale as you lean your torso back. Exhale as you raise up.
