The 5 types of spinal stabilization exercise program. (A) Upper-body extension. With pillow supporting abdomen, clasp hands behind back and lift body off floor. Keep chin tucked while lifting in prone position. (B) Alternate arm and leg lift. Keep knee locked and lift leg (8–10in) from floor, along with opposite arm in prone position. (C) Alternate arm and leg extension on all fours. Raise opposite arm and leg in quadruped position. Do not arch neck. (D) Diagonal curl-up. Keeping arms folded across chest, tilt pelvis to flatten back in supine position. Lift head and shoulders from floor while rotating to 1 side. (E) Curl-up. With arms at sides, tilt pelvis to flatten back. Raise shoulders and head from floor in supine position. Use arms to support trunk if necessary. Curl-ups excel at increasing the activity of the rectus abdominis muscle, but they produce relatively smaller oblique muscle activity.
