Alternate working your back and abdominal muscles with this simple routine. You can easily perform both of these moves at the end of your weight- or cardio-strengthening program to keep your core muscles strong and flexible. You will gradually be able to hold each position longer, but remember that patience and consistency will yield far better results than forcing your body to hold new positions too long, too soon.

2 To strengthen your abdominal and upper body muscles, lie face down on a padded surface or a mat in the same position as at left. This time, press down into your forearms as you lift your waist, hips and thighs off the floor. Engage your abdominals to prevent your lower back from overarching. Hold for 8 to 12 seconds.
