Practice juste Ollieing onto the ledge without pushing

I’d say to try ollieing on the edge and then try riding ins to a curb and try it and then try ollieing on to it and see if it locks in

Put your board on the ledge and get used to how it feels, also tighten your trucks

Make sure you get your heelside wheels pressing as close as you can to the ledge, this gives you a more stable lock in.

Ollie later and don’t push forward
