The Ultimate Self-Defense Championship was a competition in which six martial arts YouTubers competed against each other in seven self-defense challenges to find out what works, what doesn't and who would become the ultimate self-defense champion.  The organizer of this event was Rokas Leo who trained Aikido for 14 years and eventually realised that that art didn't live up to what to the promises. He made the switch to MMA training and has had several amateur MMA fights since.   My previous interview with Rokas about his evolution from Aikido to MMA: https://www.grapplearts.com/aikido-vs-mma-rokas/ Watch the first season of the Ultimate Self Defense Championship on Youtube for free: https://www.youtube.com/watch?v=JU3nOrEfN70&list=PL4FJXg8RNp-mqVhFpncyMk4rANel-TRa9 Contribute to The Ultimate Self Defense Championship Season 2 here and get early access and extra footage: https://www.indiegogo.com/projects/ultimate-self-defense-championship-season-2#/ Find out more about Rokas on his site: https://www.martialartsjourney.com/
