Well, I "practice" falling a lot! Ha ha. I guess for those that are beginning to skate, this is a good lesson. I know it's taught in the early learn to skate classes for both adults and kids. It is important to try to remember certain things, like not catching yourself with your hands, or tucking your head.
However, in reality, most falls I take are one of two kinds: A fall that I sort of know I'm going to fall (like a jump or spin) or something that is random and silly that just happens.
The first kind of fall happens every session I skate. I guess that's practicing it. But especially on axels or double sals right now, I kind of have an idea when I'm in the air of what's going to happen, and I can adjust. Realistically, those falls don't hurt that badly anyway.
The second kind of fall, I don't care how good I am or how much I practice falling, they're going to happen and there's not much chance to react. It's not like I start going down, try and stop it, or fumble around for awhile and then fall. It's pretty much hey, I'm doing footw - boom. My best one I was standing and talking to someone by the boards, and then I wasn't. Never could figure that one out. I can't replicate those falls to "practice" them and if they're going to hurt, they're going to hurt.
Maybe by falling so many times, I've unconsciously learned how to fall not to hurt myself. But I definitely don't actively practice just falling.
