The basic crunch exercise for the abs targets the rectus abdominis muscle. Although it seems simple, many people don't perform the basic ab crunch properly. Using good form when doing an crunch makes this a much more effective abdominal exercise.

How to Do the Basic Abdominal Crunch

  • Lie on your back, bend your knees, placing your hands on the sides of your head.
  • Contract your abs and flatten your lower back against the floor.
  • Slowly lift your shoulder blades one or two inches off the floor.
  • Exhale as you lift, keep your neck straight and chin up.
  • Hold for a few seconds (don't hold your breath).
  • Slowly lower while keeping your abs contracted.
  • Repeat up to 20 reps this perfect form for each rep.
  • To make it more difficult, use an exercise ball.
