180s and 360s just won't come around. Usually it's not a technique problem — your body simply doesn't know the feeling of spinning in the air yet.
The thing is, that's hard to practice on snow. Falling hurts, so you can't really try it over and over. That's where an off-season trampoline comes in: you can repeat the same motion safely, dozens of times.
【First, jump straight up】 Before you spin, just jump straight up and land in the same spot. Do that a few times.
If your body tilts, your axis drifts the moment you start to turn. Keep your hands close, eyes forward. Pushing up through your toes is enough.
【Start with a half rotation】 The instant you jump, send your shoulders and arms toward the way you want to turn. That's the lead rotation. It's the same body movement as an FS180 or BS180 on snow.
Bring your chin toward your leading shoulder and look half a turn ahead. When the landing comes into view, open your arms slightly and the spin stops.
【A 360 is just an extended 180】 You're not doing anything new — just the 180, bigger and faster.
Take a deeper lead rotation and use your jump height. Then pull your arms and knees in. Like a figure skater's spin, the tighter you tuck, the faster you turn.
Thinking "spin twice as hard" only makes you tense. Pull in, and let it accelerate. Once that feeling clicks, it suddenly comes together.
【Build it up safely】 Don't reach for height early. Stacking up low half-rotations is faster in the end.
Practice the direction you'll want on snow. And always check the facility's rules and the condition of the mat.
The feeling you build on a trampoline carries straight over to snow. Touch even the entry point this summer, and your first run of winter will already feel different.
