I mean, I get that running is important in boxing where they fight longer and where there isn't as much to learn as in mma anyway, so they have time for that, but can somebody fucking explain to me why MMA fighters are still running?
They have so much things to work on technically, there is noone in the world who has elite level boxing, kickboxing, wrestling and bjj at the same time, so why don't they try to work more on technique.
And as far as cardio goes, there are so many better/more specific ways to work on that.
Bjj drills, non stop flow wrestling, high intensity Dutch drills on the bag, if done correctly, those things will ramp your heart rate up as much as running, in addition to developping your technique and not putting wear and tear on your body as much as running does.
Grapplers don't run (not speaking about wrestlers but about jitters, Adcc guys). Some intelligent kickboxers, like Bazooka Joe, don't run either, for the very same reasons I just enounced. So why in the world would guys who have such big holes in their game as far as technique goes (which is normal, you can't be good at everything) still waste time with running?
Btw, I'm of course speaking about long distance running, not speaking of short sprints, which can be useful, though not indispensable
