Oh wow, you go to a gym 3 times a week. Dada has been in literally dozens of bare-knuckle street fights. He does this FULL time, it's a hobby for you and he is 300 lbs.
And your assesment of most Sherdoggers being fighters? Wow you really gotta get out of moms basement man.
Even CM Pink would destroy 99% of sherdoggers and casual martial artists....why ? Simply because those guys do it 8-10 hours a day. You go to class 4 times a week for an hour and think your Mike Tyson. Otherwise, unless moms feeding you, you got a sedentry or non related physical job.
If you train full time as an athlete, no matter the sport you will most likely kick someones ass who is casually practicing martial arts, that's just a fact homey.
Try to let mom give you a few more free hours outside and you'll see things better.
