Ab set-up

  • Start sitting up with your legs together and your hands held behind your knees.
  • Pull your naval in as you curve your lower back down toward the floor, and lift your heels up.
  • Use your abs to crunch forward 10-15 times.

Extend Your legs

  • Straighten your knees as you raise your lower legs so your toes are pointed toward the ceiling.
  • Contract your abs in as you crunch forward 10-15 times.
