INSTRUCTIONS FOR USE
Lie down on the reclining surface with your legs bent (starting position 1). Lift your upper body slowly and steadily towards your knees and back down again. Keep your arms down by the sides of your body.
For a more vigorous workout, keep your arms crossed across your chest.
Holding your hands at the side of your head gives your body even more of a workout. Your elbows should be bent and held as far from your head as possible.
Get into starting position 2. With your knees slightly bent, push your hips against the curved surface, lower your upper body down and lie flat against the surface. Now slowly lift and lower your upper body in a steady motion. Keep your arms down at the sides of your body.
For a more vigorous workout, keep your arms at the side of your head.
Pull your shoulder blades and elbows back slightly when straightening your upper body for maximum effect.
