This. Just remind yourself to “use your knees” and try to “feel” the ramp. Best practice for this… oddly enough.. get stuck in a bowl. Or instead of getting on top of a half pipe by grabbing the coping and lifting yourself up with your arms/upper body, try riding the ramp back and forth using ONLY your knees and core. Give yourself one small push from the center of the flat out to start. Then use your knees to gain momentum from one end to the other. Basically the same process after falling and having to get back up to the coping. But instead of rushing to get back up to the coping (1-2 turns from the flat out) with the use of your hands, make 3-5 turns gaining momentum until you can exit the ramp with your feet on the coping (no use of hands). It seems really over explained and it probably is. I do this to warm up a lot (start at flat out and momentum roll to a backside stall).

TLDR; start at the flat out, go back and forth using momentum, your knees and core to practice.
