This guy is not only informative, but entertaining. I wish I was famous just so I could endorse this guys videos. The instructions are all legit and they are permeated with hilarity that makes you really remember each tutorial. I found this app after subscribing to his YouTube channel and Im glad I did. It has IAPs but they are all worth it. However, the free videos (and there are more than just a few, its not a ripoff) and a little training are more than enough to make an amateur into AT LEAST a novice. You gotta start somewhere right? Now excuse me I have to get back to shadow boxing. My actual shadow.
