A fully grown silverback can reach 6'0 standing upright and 500lbs, can tear a man apart very easily. Your 190lbs of lean muscle will do nothing against this beast, not to mention that it can bite too.. it's not just hands and feet that will tear you apart my masculine friend. You would literally be like a toddler trying to fight this thing, you MIGHT get a good cheap shot on it, but you can't knock it out, it's skull is 4x more dense than yours too, so to give it a concussion you would need to hit it extremely harder than anything you've hit in your life without breaking your hand. I would honestly say that even you being 5% body fat, MMA fighting, bodybuilder, etc.. add more if you want, pakour or something, i don't care. You have about a 1% chance of winning against a gorilla that was actually after to kill you. most likely it would just crush a few of your bones and

hello there
