How to
Step by step[Safety first] Wear a helmet and back protector, and learn this only at a facility with an airbag or foam pit.
A backside double has a long blind phase where your back faces the ground, so trying it straight onto snow risks landing on your back or the back of your head.
Make sure the prerequisites are solid: you can land BS Cork 540 consistently (at least around 50 clean ones) and you have already spun a flat BS 720.
You need both the 540 spin pattern and the final half-rotation of the 720 already in your body.
Take a straight approach with plenty of speed, and choose a larger kicker with long airtime.
With this much rotation, short airtime means you cannot finish the spin and you come down on your back side.
Just before takeoff, wind up by turning your upper body slightly the opposite way (away from backside) and drawing both arms back toward your rear foot.
This load is your run-up for the spin; the tension you build here becomes the spinning momentum.
At the lip (the tip of the kicker), extend both legs to pop straight up and, at the same instant, swing your loaded upper body and both arms around toward the backside.
All of your spinning momentum is set at the moment you leave the lip and cannot be added in the air, so swinging firmly at takeoff is what sets how far you rotate.
Right after leaving the lip, drop your rear shoulder (the shoulder on the side away from your direction of travel) diagonally down and back.
This tips the spin axis off vertical and adds the flip element that makes it an off-axis rotation. Too little shoulder drop and you only get a flat BS 720.
As soon as the rear shoulder drops, pull both knees to your chest and tuck both arms in front of your body to make yourself compact.
The tighter you pull your arms and legs in, the faster you rotate for the same momentum. Because the blind phase of a backside double is long, tucking as early as possible after takeoff is what lets you finish safely.
Start your gaze looking diagonally down over your rear shoulder, and don't force your neck; let your head follow your body's rotation.
When the landing slope below the kicker comes into view in the second rotation, release the tucked knees and arms, extend both legs, and land regular stance with both feet at once and weight slightly toward the front foot.
Tips & common mistakes
In the app — learn while you logAll of your spinning momentum is set at the instant you leave the lip and cannot be added in the air. So the bigger and quicker you make the sequence of wind-up (counter-rotate the upper body, draw both arms back) and then swing back toward backside on the pop, the more rotation you can finish.
Landing on your back side -> the swing-back at takeoff is too weak so you lack spinning momentum, or the tuck is too late -> build a bigger counter-rotated wind-up before takeoff, swing both arms hard toward backside on the pop, and tuck the knees and arms in immediately after leaving the lip.
