My name is Ann Kaczka, I've been practicing Parkour since 2007. My first day training was with David Belle at the New Yorker festival. And since then I've trained solo in Thailand, climbing trees on the streets of London and Paris. And now I'm back in New York City. And today I'm here to talk to you about Parkour. So, a monkey vault, you're going to be approaching the obstacle from head on. Going to jump. Plant both of your hands, probably a little more than hip distance apart. Jump through, tucking your legs to your chest and push off, finally, to get over the obstacle. The difference between a monkey vault and a cat pass, pretty much, is that the monkey vault is more of a progression into the cat pass. With a cat pass, you're going to get much more height and distance out of it. You're almost diving at the obstacle. With the monkey vault, you're going to be starting closer to the obstacle. You're going to plant both of your hands onto it, a little bit more than hip distance apart, and jump, bringing your knees to your chest. Push off with your hands. You're going to be up and over. So, to approach doing a cat pass, there's a bit of a progression that we can show you. You're going to approach the wall, place both hands, palm down on the wall about hip distance apart, and just hop up and try and put one foot on top of the wall. Next, you can try and put both feet on top of the wall. And then, finally, attempt going over the wall once you feel comfortable with those two progressions.
