The first few days are never good. I remember that I was so sore that it hurt like absolute hell just to get in and out of my car.
What I did for chairlifts initially:
Tell yourself that you'll ride straight off the chair. Expect, and welcome acceleration. Keep your balance or lean a little forward... and just ride straight out.
Keep your knees bent, even crouch a little if you have to.
If you ride straight.... you'll *eventually* come to a stop, because it always flattens out after you clear the lift.
Never panic... unless you're going to hit someone or something. If someone beside you bumps your board.. ride straight. If someone besides you crashes... ride straight. If there's a little kid ahead of you, or a giant metal bench... THEN you bail. If you can apply brakes, do it.. if not, just bail, being careful not to break your fall with your arms, tailbone, or skull (xD). Then cuss out the liftie for not doing his/her job to clear the ramp
Most crashes off the lift happen because people panic and lean back.
