Ground Frontflip.

1. Pick a soft, freshly groomed slope of medium pitch or steeper, and ride straight on at a moderate speed without turning.

   Too little speed means too little air time, so you land on your head before completing the rotation. Secure enough speed first.

2. Just before takeoff, bend your knees well, drop your hips, and sink down with your weight spread across the whole board from the ball of your front foot to the heel.

   This loads up your spring.

3. Using that loaded rebound, extend both legs explosively to push down through the snow (drive the front foot like an ollie/nollie press), and at that instant keep your lower body from moving forward while you tip only your upper body, from the sternum up, down and forward.

   Stopping the lower half while sending the upper half forward is what creates the front-rotation momentum.

4. As you leave the snow, send your gaze just beyond your front foot to the snow ahead, tuck your chin, and start tumbling forward head-first.

   The spinning momentum is set at the moment you leave the snow and cannot be added in the air.

5. Once your body has tipped forward, pull both knees to your chest and your heels toward your seat to make your whole body small.

   The closer your arms and legs are to your center, the faster you spin for the same momentum, so this is where you speed up the rotation.

6. Past the half-rotation, when the slope below comes into view, spot your landing and open the tucked knees and heels slightly to extend your body and slow the spin.

   The more you open, the slower you rotate.

7. Level the board parallel to the slope and land on both feet at once.

   Bend your knees deeply on impact to absorb it, then bring your torso back upright.
