American Ninja Warrior - 4 steps to training - Parkour

At the moment, I'm doing one beginner class of Parkour a week, and I'm usually sore for at least 2 days afterwards. It's really fun though and I'm really not that bad at it. I've got a good leap and I'm strong, I can usually muscle my way through things (not ideal) if my technique isn't great. Some of the other dudes in the beginner class are just amazing, it's very inspiring. I actually can't wait until I'm conditioned enough to go more than once a week.
