The vertical leg crunch is another effective move for the rectus abdominis, the external obliques and internal obliques.

How to Do it

  • Lie on your back and extend the legs up with knees slightly bent.
  • Contract your abs and raise up until your shoulder blades leave the floor.
  • Keep your chin up; don't pull on your neck.
  • Keep your legs in a fixed position.
  • Lift your torso toward your knees.
  • Lower and repeat for 12-16 reps.
