Hahahahaha. Have you ever been to a boxing gym?
Of course weight classes are there for a reason. A good big man generally beats a good little man, it's been that way almost 90% through bxing history. However a great little man beats a crap big man, it's also been that way throughout boxing history.
What's your height/weight? How do you think you'd fair against a professional, world class boxer your own size?
It's funny you're a karate boy, karate was the first martial art I did around age 9. Karate is ***. Karate tournaments are not full contact, ***, not even real fighting.
I then did taikwondo - got to red belt, one away from black, got bored, then did thai boxing at around 14/15. Thai boxing is hardcore, that's full contact.
In my late teens I started proper boxing. Even with a martial arts background I got a ****ing shock when sparring for the first time with an experienced amateur who was crafty as ****, and hit harder than anyone I'd ever fought, and had excellent defense. And had actually TRADED punches for years - do you understand that part? Actually fought properly, not practiced, not tap sparring, actual fights, where you punch each other in the face.
Martial Artists don't get hit with regularity, and can't throw a punch, and generally have no defense. Training for defense against throws and knives etc, but can't even slip or parry a punch lol.
When I used to go the the Kronk Gym that opened in kentish town, kick boxing/TKD boys used to come in all arrogant, and get KTFO by just an average amateur.
Being that you're obviously superior, how do you feel about me putting you in touch with a boxing gym near to you, and sparring a pro fighter?
