Can someone reure me about using poma lifts on a snowboard :-(?

Luckily, as you get better, you won't need the poma lift since most of the higher terrain is served by chairs. For now, make sure that you support all your weight with your legs and let the poma lift pull you: don't sit on it. Also, don't get up on your edges, because they will catch, and you will fall. Make sure you point sideways so that you aren't torquing your lower half around, which will once again lead to a whitewash.
