give athletic anorexia a chance!!
no.
fwiw I absolutely hate bjj.. when I was boxing at ATT, I tried a few bjj classes (no-gi and gi). In the gi class I had several 250-300 lb. men eventually just lie on top of me while trying to choke me out. In the no-gi class I dislocated my pinky toe completely while doing drills on the mat, oh that was after doing like 10 minutes of chokes. hahaha. At that point I realized, I will do everything to stay on my feet if I have to defend myself. i'll stick2boxing. lol.
If you end up training with some dedicated wrestling/bjj/mma folks, you'll find some great training partners.. Those people are nuts and usually train pretty hard. It's a cool group of people.
pC!
yeah it looks like a recipe for lots of injuries. OTOH, i want to fight someone. the size difference thing could be kind of cool even, at least in sparring, because you have to play to each other: the class i watched in saigon had big dudes grappling with little women and they just made it work. obviously the guy could just crush the woman if he wanted to in a lot of cases, but that's not what the training is about, and people were working together on it. seemed like fun.
cool.
btw, "i want to fight someone" -> meaning, you want to actually fight in a sanctioned match?
if so, you're smart.. that is a somewhat of a problem. Eventually you'll worry about your brain and such, it happens to pretty much every "smart person" who wants to fight. Progressively harder sparring will leave you with headaches and such .. smart people eventually worry.
fight training itself is fun/beneficial though.. it's the hard sparring component of preparing for a real fight that starts to make you think..
I've never had real migraines in my life, other than when I was hard sparring (hours after matches) ~2-3x/wk for several months.. And I barely got hit, had great defense. But even blocking punches (covered up) can rattle your brain etc, and especially if you get caught with clean shots... even with head gear etc. Head gear can even make it worse, apparently (some studies find) - mostly due to absorbing more shots and increasing the surface area for shots to land IIRC.
as for sparring bigger people, that's how I got hurt. I was < 150 sparring lots of people 170-185. Weight difference and bone structure are huge factors. I ended up getting hurt by punching someone hard on top of their head (when they ducked down), wrecked my index knuckle. Had that person been ~150 instead of ~180, I might have been ok, not sure.. But you have to be careful of trainers who aren't actually looking out for you, it happens alot in these fight gyms.
but ya there's a difference between light sparring and hard sparring .. light sparring with bigger people is fine as long as they aren't psychopaths (who try to hurt you out of nowhere). But hard sparring with much bigger people?? not a fan..
anyway not trying to scare you away from it, just figured i'd mention some stuff based on my experiences.
also i'm talking about striking, not BJJ.. when I see "fight" I just immediately think striking. So sorry if i'm off.
