  • Start within a v-sitting position on the floor with your legs bent in front of you.
  • Keep your back straight and lift your hands slightly off the floor, and raise your feet up and draw towards your chest. This movement is “in”.
  • From here, lean back with a straight spine and touch your shoulder blades on the floor slightly, with the same momentum you also want to extend your legs straighten.
  • Your blades are touching the floor, stop that leaning back and hold this “out” position.
  • Then lift your body up away from the floor and draw your knees in towards your chest to return to the “In” Position.
  • Repeat this “In-Out” movement in a controlled way and do it until failure with 3 sets.
  • Tips

  1. Drop your butt down really low so that it breaks parallel as you land in the wide stance (”out” portion of the exercise)
  2. Wear a weighted vest to increase difficulty.
  3. Perform “Out-And-Ins” for a better experience.
