when most people try fronts they just huck forwards as hard as you can. lots of people can land them that way but its defiantly harder then this way. when you take off, dont throw yourself down. throw yourself out so you are flying through the air. then tuck into a ball and finish your flip. learned them last weekend and they are mad fun. good luck
I actually just got them dialed today for the first time. I was trying them off a 10-15 foot table at first and just getting worked. Then I tried one off of the knuckle of a jump and stomped it first try. If you think about the physics of it, most "jumps" are shaped so that backflips are easier. Front flips are easier off of a drop of some sort. I would say try them on a drop or off a knuckle first, learn them well there, and then take them to a jump.
If you do the ball method (hucking and immediately tucking into a ball), grab the backs of your legs to ensure you hold your tuck. But definitely get your arms back out in front after you complete the rotation. This way, you will flip faster, but won't land too back seat.
For fronts you want to let the jump give you pop before you huck the flip I know it sounds stipid but wait a split second before you flip after you leave the takeoff, that way yo can get enough air to bring it around.
the way i was taught, was to preset my arms. i would raise my arms in the tranny, and put so much forward pressure in my tips of my skiis my tails actually lifted off the ground. on the lip of the jump, extend as much as you can, and get a really big pop and do a superman. after launching and having a moment of super powers, tuck up really hard and extend when its time to extend. thats the way i learned, anyway. good luck with fronts, dont hurt yourself, like someone i know did.
