Follow the instructions below to perform this exercise:
Anchor: Secure the band(s) to the door with the door anchor at the bottom of the door.
Bands: Attach each end of the band(s) to an ankle strap.
Body Positioning: Fasten an ankle strap around the bottom of each foot (with the ring on the bottom of your foot), and lie on the floor on your side, with one foot stacked on top of the other. Move far enough away from the door so that the band is starting to stretch. For stability place your bottom arm straight out to the side with your palm down. Position your top arm with your hand behind your head and elbow pointed straight up.
Pull your knee that is on top away from the door up until your thigh is perpendicular, and calf is parallel with the floor. At the same time crunch your body to the side (up) and touch the elbow of your top arm to your top knee.
POINTS TO REMEMBER
1. Do not pull your head as you crunch your body to the side.
