Ok so I'm terrible at explaining things, but I'd love to try and get you better cause you cool <3

So instead I made a replay to help have a basic line to help me figure out what to explain. First off, the arms are used to move back and forth to help balance and style. The glutes are meant to help keep balance and turning. The chest is not used often, i recommend not using it to run, it messes it up for you and looks odd. the feet help you keep from falling over, you want to try and keep them flat if you can. The lumbar is last resort if you are trying to keep balance and you are almost falling. If you have trouble running because you are falling or something, put your arm down to help push yourself back up. Also mostly use Shift Space to help keep situated and in the right position. It all comes with practice <3

Also I'm a parkourist, so if you ever need any more help, I'll do me best <3
