Sometimes when I try it earlier in the day, I am able to get up if I keep my hips real low and give myself a good push against the snow behind me, then I can go from a low crouch to standing while the board starts to go in motion. But as soon as I get a bit fatigued, I just lose balance and fall as soon as my butt leaves the snow. I still have never managed it by myself with my heels properly dug in so that I don't slide around while standing.
