Sit on a mat or cushioned floor and raise your legs up slightly to make a V with your body.  Hold the pumpkin with both hands out in front of your body and rotate it side to side touching the ground on each rotation.  If you need to place your feet on the ground continue to exercise with your upper body arched back and abdominals engaged.

Seated: Keeping your back straight hold the pumpkin out in front of your body.  Twist from side to side directing the pumpkin downwards.
