Master Carlos Machado, nephew of Jiu Jitsu founder Carlos Gracie, has been uploading some old instructional videos recently on his YouTube channel. I’ll post links to all of them as I think they are simply excellent. Thanks to Master Carlos for these. I’ve gotten to train with him several times over the years at his school and at various seminar locations. Excellent teacher and you should seek out any training opportunities with him.
You can find another excellent video of his BJJ Globetrotters’ seminar here. Focus for the seminar was crossbody escapes and was filmed on location in Iceland.
