If you experience back pain with any of these ab exercises, stop and check with your doctor before continuing.

1. Tilt your pelvis. Lie on the floor, arms at your sides and knees bent, feet flat on the floor. Next, press your lower back to the floor so that your pelvis tilts upward. Maintain this tilt as you straighten your legs by slowly sliding your heels along the floor. Stop when you can no longer hold a full tilt position. Hold and count aloud to six. Bring one leg, then the other, back to the starting position, maintaining the pelvic tilt throughout. Hold the starting position for six more counts. Relax. Repeat 12 times.
