If everyone who is reading this doesn't know who JPMBujusu is, it's Jim McCann who teaches ground fighting at Hoch's seminars. If you never attended one of Hoch's seminars with Jim teaching ground fighting techniques, that alone is worth the price of the seminar. He also has an awesome DVD out you buy here at Hoch's, just click on the icon on the left "McCann Ground Fighting Level 1". He's also available for seminars at your place besides running his own seminars several times a year at his gym a little of north of Philadelphia PA. I'm currently training with Jim at his place 3x/week. I've been doing sport BJJ and MMA at another gym until I met Jim last year and he has really elevated my ground fighting and boxing techniques. I hired him last year to do private lessons when I was getting "beaten" up too much at my old gym. If you want to learn sport BJJ from him, he'll teach it to you, but where he really excels is dirty fighting. Whether on the ground with his infamous neck cranks or standup boxing or fighting. If you get caught in a real fight situation, you'll be glad you took lessons from Jim or the next best thing, attend both a seminar and buy his DVD. His DVD is good but doesn't do the man justice without seeing him in person. I have worked with Jim McCann 3 to 6 days a week for almost a year and I'm still amazed at the information he provides. As fast, quick, and knowledgable he is on the ground, he is quicker as a boxer. He dances across the floor like he's floating on air. He moves fast and he's smooth. Please, I'm not trying to be biased, I'm just impressed with the man. His DVD Ground Fighting Level 1 has a lot to do with getting your opponent off of you. Techniques that really work. If you have ever been on the mat, you know how it sucks when someone is on top of you. This is what this DVD deals with, getting the guy off of you. Well worth the money, I'm glad I own it. One of the better DVD. He starts off slow showing you the technique several times solo, then he has another instructor as his opponent, he again does it slowly several times then finishes doing it at real time speed. Very easy to follow and understand. The quality of the production of the DVD is diffcult to do better. It's a DVD you watch once and continually go back and re-watch especially when you start slipping and can't get your opponent off of you, your glad you have his DVD on your shelf to re-watch before you go back to the gym to fight again and say "Bring it on!"
