Between The Olympics has one of their great posts linking results and videos.
That post includes this bonus clip on an interesting training set-up:
… Anastasia Grishina training vault. She’s doing a Podkopayeva and then a half turn after landing- will she be attempting the front “layout” full soon?
Click PLAY or watch it on YouTube.
I’m a big fan of vaulting off a TumblTrak, without a spring board.
