How To Do:

  • Lay flat on your back with arms at your side.
  • Straighten your legs, squeeze them together and slowly lift them towards your head.
  • Be sure that your shoulders, arms, and head lie completely flat on the floor.
  • Do not lift them as you lift your legs, and your body and legs should be at about a 45 degree angle.
  • Slowly roll your spine, leaning your legs slightly to the right. Make sure your legs are squeezed together.
  • Move your legs back to the center without putting them on the floor. Make the same lean to the left.
  • Continue going from side to side. Complete 10 reps, three sets, inhaling slowly and freezing for two seconds on each side.

How to Do:

  • Lay on the floor or a bench with your legs straight out, arms stretched above your head, toes pointed towards the ceiling.
  • Raise your arms towards your toes as you raise your legs to a 45- to 90-degree angle, keeping your shoulders off the floor.
  • You should bring your arms way up over your belly button so your body looks just like a jack knife.
  • Then return back to the floor or bench with your legs and arms stretched out. Do 40 reps.
