Backside 720.

1. Build solid speed on a medium-to-steep, well-groomed slope.

   A BS720 needs enough forward travel and pop to complete two full rotations, so you want both speed and height.

2. Before you pop, sink low with your knees bent deeply (around 90 degrees) to load up.

   At the same time, wind your upper body and arms slightly the opposite way (toward your frontside, the direction your belly faces) to coil up tension.

3. Press the heel side of your back foot into the snow to flex the board, then release that rebound to pop straight up.

   As you pop, unwind your coiled upper body hard toward your backside, turning your hips first and letting your shoulders and arms follow. Your spin momentum is basically set the instant you leave the snow and you cannot add to it in the air, so create all of it right here.

4. Right after takeoff, send your eyes toward the spin direction (over your back shoulder) and lead with your chin so your head turns first.

   Backside spins go blind for a moment twice, so keep your head turning even when you cannot see the landing instead of stalling.

5. In the air, pull your arms in front of your chest and tuck your knees up to make your body compact.

   With the same momentum, the tighter you pull your arms and legs toward your center, the faster you spin, which buys you the room to finish both rotations.

6. Once you pass one and a half turns (540 degrees) and the landing comes into view below, slowly open your arms and extend your legs.

   Spreading out slows your spin, so use this to stop rotating and settle your stance.

7. Line the board up with your direction of travel, bend both knees to absorb impact, and land in a normal stance with your weight balanced evenly over the middle of both feet (the arches).

   A tilted spin axis makes you wash out, so keep your head and chest up to hold the axis vertical all the way down.
