The V-up is a bodyweight movement that targets the muscles of the abs, the rectus abdominis or "six-pack" muscles in particular. It is similar to a suitcase crunch, but the lower back lifts off the ground at the top of each rep. It can be performed for time or reps in the ab-focused portion of any workout.


  1. Strengthens the abs and hip flexors
  2. Increases core strength and stability
  3. More difficult than standard crunches or reverse crunches
  4. Requires no equipment

V-up Instructions

V-up muscle diagram
  1. Lie flat on the floor (or exercise mat) on your back with your arms extended straight back behind your head and your legs extended also. This will be your starting position.
  2. As you exhale, bend at the waist while simultaneously raising your legs and arms to meet in a jackknife position. Tip: The legs should be extended and lifted at approximately a 35-45 degree angle from the floor and the arms should be extended and parallel to your legs. The upper torso should be off the floor.
  3. While inhaling, lower your arms and legs back to the starting position.
  4. Repeat for the recommended amount of repetitions.

Variation: If you are really advanced you could use a medicine ball for added resistance.
