Any tips/suggestions? I honestly cannot even begin to figure it out.

Can you ollie out? Get that on lock and it might start making more sense in your head

Actually, I never even thought to try haha. I always just slide off or shuv it out. Good call. Probably should work on that first

just reeeelax those fingers all the way. if you let the tailslide sag down a bit before you pop it will make it way easier to pop since the leverage will naturally be much more than if you were pressing on the tail. Also maybe try switch front nose kickflip out.

The secret is the relaxing of the fingers, just like Parrish say, when you pop out of the rail don't try to slide your fingers to do a conventional kickflip, try to slide your fingers to you, i mean, exagerate a little bit the move, and step by step you will get able to do it more relaxed
Look at 4:10, he's doing a bs tail hardflip out, but is the same technique, go with a relaxed bs tail, and at the final just do an explosive and a little exagerated move sliding your fingers backwards

Thanks guys! Definitely going to take some practice. I was trying to flick it more like it was a regular kick flip.

And the dude in that video is so good
