Now, in order to be one of the world's greatest grapplers, you not only need to put in the mat time (i.e., the perfect technique), you need to train, and train hard. In the famous words of grappling great Erik Paulson, "Conditioning is one of the few things you can fully control."
The world's best grappling athletes are competing this weekend and they've been training at a sick pace for months. Take a look at Andre Galvao utilizing the Bulgarian bag in preparation for this weekend's ADCC tourney. If you're mildly perplexed about what the hell a Bulgarian bag is, you can read about it here. Or you can get my quick version: it's a heavy (usually leather) crescent shaped bag that has various handles and straps used for overall conditioning and grip strengthening exercises. It was developed by a US Olympic coach and Bulgarian wrestler, Ivan Ivanov.
So watch Galvao go through two minutes of pure hell and lament, realizing the only exercise you had today was sucking the orange off of your processed cheese food encrusted fingers and clicking on our site (which we appreciate very much).
And, not to be outdone, Andre's Atos teammate, Rafael Mendes, has a ADCC training video of his own.
And, let's not forget Team Popovitch. Major props for Pablo's use of Indian Clubs. Novel!
