I trained outside of a gym exclusively for two years before joining a gym. I def feel it helped me advance way quicker, because I could set my curriculum to my and my training partners weaknesses and focus on 10p. But when you feel like your pretty solid its good to go test yourself against other systems weekly. My Hotbox ,which used to be in a shed and the back of my truck, is now in a traditional jj and mma gym. We are constantly forcing eachother to adapt and progress by the mix of styles and its a pretty sweet environment. But yeah, I love it when people think the self trained are clueless. Especially when they are pro members that have mtrg and mtt memorized with thousands of reps. Do your thing Tony.
