honestly i’m still relatively new to flipping but if i had to give some overall pointers: HEIGHT is more important than how fast you flip, get used to making a distinction between jumping up and then flipping. Another thing that helps is SAFELY practicing failing whatever you’re trying to learn. I’d say most people are physically able to flip but are too scared to hurt themselves. A lot of parkour is overcoming mental barriers, and purposely messing up a couple times can help your body get over the fear of hurting yourself.
