it helps if you have front 180s down good then you just 90 up to it and bend your knees to keep your foot from falling off just try to Ollie up to the rail and turn stationary

You just have to bend your knees

What helped me was I started board slides on parking blocks first then I just do the same thing on flatbars and other things

Just be really confident on your FS 180s, then tell yourself to commit or you have to break your board. That's what I do

Go faster
