umm for a lookback you have to do a turndown when doing something frontside (jump a hip, air a quaterpipe, spin). The regular way of doing turndowns that's easier for 99% ppl is when you (in case your goofy) turn the bar left and the deck on the right. But be careful that the desctiption of the turndown as "tweak the deck sideways and do an x up" is actually the worst one ever, you also should push the bar down (TURN it DOWN) to make the scooter sorta inverted. Oh, and add in some style and there you go.
