Tantrum

Tantrum is a heelside backflip. The board trips as the rider squares up at takeoff, releases the back hand, and lets the flip move backward instead of rolling off the edge like a backroll.

Edge in, flatten and square shoulders at the top, push tall, bring hips up, look back through the flip, spot the water, and absorb the landing.

Practice re-entry ollie or trip-pop drills, trampoline backflips, and consistent heelside approaches before trying the full invert.
