Renzo Gracie has an online course that has a new technique every day of the week and covers a theme, like mount week, or defending the pass. Good stuff. Like 10 bucks a month or pay for whole year. Also has takedowns, self defense, diet, mindset, no gi stuff and in the future hell have mma stuff too I guess. Good shit. I have a subscription and man it doesnt disappoint. Its alot of basics so far(just started in November 2017) but I have a feeling he cover advanced stuff as it evolves. Highly recommended.
