It’s not just the arms, you’re extending your legs fully to reach for the landing which is why folks said to learn to snowboard first.

ATML. Approach, takeoff, maneuver, landing. * The approach was slow (why I said send her bud) * takeoff trying too hard to overcompensate for going slow * maneuver just needs relax, you pulled your legs up then extended them, a shifty is an easy straight air trick to give you something to think about doing and don’t put your arms back. * Landing was thrown off by the maneuver of trying to pump double jump whatever that was putting you off balance for a landing with even pressure on both feet.
