Another thing VERY overlooked by people first starting in grappling/BJJ is that regular cardio (sprints, running, biking etc) DOES NOT transition into grappling cardio. I learned this the VERY HARD way Lmao.. Sure, it helps some, but I thought I would be good considering I was running about 3 miles a day at the time, not amazing, but decent...
Brooooo, when I first started rolling I was GASED by the 2nd round, I was done.. And on Fridays was “competition training” so no drills, just straight rolling and it would be 3-5 minute rounds and every single round you’d switch partners, for 1 1/2 to 2 hours, THE WHOLE TIME... Needless to say for 95% of that class time I was just a human dummy the other guys would use to practice their submissions lmao I was helpless.. I mean, I was helpless as it is coming into round one being fresh, but by 30 minutes in, id never felt my body tremble like that.
I remember one of the 135lb MMA pros (he’s not even a black belt yet, I think he was purple belt) tapped me legit 8x inside a single 3 minute round and I’m 40-45lbs heavier.. And the STRENGTH on those guys, it’s incredible. Fuck a 170lb guy that can squat 500lbs or deadlift 600 for reps... People need to Grapple with a 170lb black belt if they want to know real strength, nevermind the 200lb+ guys, those are hairless gorillas that just look like humans..
Anyway, the only way to build grappling cardio/conditioning is to grapple.. A LOT.. lol
