Great System for All Levels of Experience

I came here from Greg’s YouTube channel, and I got so much value from his free content that I had no qualms about buying his course. And what a great, comprehensive course it has been. This is the type of thing that can take you from beginner to intermediate, or intermediate to advanced. You can win fights with this system. It is great at creating dilemmas for your opponent, then having answers for every one of their responses. From striking, to back takes, to takedowns. I’d buy a jiu jitsu course if he had one. Greg is 1 of 1 when it comes to teaching concepts. Don’t even hesitate, invest in yourself.

Great System for Fighters

This is a great system for any fighters who need to level up their game. In my case, I can do all the punches, kicks, and takedowns, but there wasn't much rhyme or reason. I would throw in a combo here and there, implement a strategy for a couple days at most. With this, its a proven system that creates dilemmas for your opponent, and can also keep you safe. It's also very simple and easy to follow. If you stumbled across this, you're lucky.

Revolutionary way to systemize learning MMA & self defense!!

This is by far the best & most comprehensive video series on how to easily learn an entire system of Full Contact fighting for Stand up, Clinch, and Grappling range! I am in no way affiliated with Greg or Devil Dog Martial Arts btw. Greg really should have Cross promoted his you tube channel and especially his book, which goes into way more detail than this, especially with grappling. The Nemean Fight System feels like an updated, better version of Jeet Kun Do that is modernized for everything MMA has taught us in the last 30 years! It isn't overwhelming to learn though, because it focuses on the highest percentile attacks, defense, etc. You'll get your money's worth in just the first 30 minutes of the 3 hour series!
