switch and nollie flips. Don't think ill ever train my body to figure these outs. My switch flick is fucked.
switch and nollie flips are tough to learn by definition - everybody seems to really struggle with the switch flick at first, but once it finally clicks, you just got yourself two new great tricks. I know what it's like to postpone learning a trick that doesn't naturally come to you, and you just can't form to the point where just the mere thought of trying it feels like a waste of skate time already (I'm the same with many, including the aforementioned backside tailslide). but I'd say those two are worth it.
just try them on and off. start with the switch flip (the easiest of the two if you're just trying to figure your switch flick out), and basically trick your brain into thinking it's a normal stance kickflip. blank the switch part out on purpose and just try mimicking your regular stance motion. since you can already kickflip, from then on it should be dead easy to figure out what you're doing wrong and work on that. think of it as learning how to do a basic kickflip again, just from an uncomfortable stance. the dreaded myth of the almighty switch kickflip is just a mental construction, it's just a kickflip. just grip the board as usual and use your ankle. try maybe 5 a day or every other day, see how close you can get. keep it fun and you'll get in on lock eventually, try it at the end of your lines once it starts coming together, casual stuff like that. then the nollie flip will come by itself.
it took me years to finally learn nollie and switch flips and by then I could already do a bunch of nollie flip and heel flip variations, just not the straight, normal nollie / sw flips. I know the struggle, just saying. but once you get it down it becomes a simple and very fun trick you just can't help but do all the time, pretending you're Keenan or PJ when you really aren't.
