we've extolled the virtues of watching great grapplers free rolling with teammates and friends. If you watch with a mindful eye, you'll glean all kinds of dope knowledge. Unlike an instructional video or a video of a competition, watching a free roll is like being a fly on the wall in the grappler's laboratory. From that, you get to see a grappler being experimental and really flow.
Check out a great sesh caught on video by our good buddies at Jits Magazine of World Champion, Rodolfo Vieira free training with his teammate, Denilson Pimenta.
(Note: Watching your coach roll with his high level guys is equally as helpful.)
