Been doing these since 2005 and many more as well. Great for all sorts of things related to all martial arts.
Ginastica natural is a body weight style program for all ages and skill levels designed by Romano Alvaro. He is a BJJ Blackbelt.
Excellent for all aspects of training where dexterity, agility, flexibility, core, balance, explosiveness, solo reproduced grappling movements and strength is required. Very cool vid too BTW. I highly recommend them especially where children are training. they don't even know they are exercising. Far too busy being Gorillas and Kangaroos lol
