Many instructors at mixed martial arts gyms are currently or were once-upon-a-time professional fighters, and that type of experience is invaluable when training a future competitor for a MMA career. It also doesn't hurt when a school brings in a professional fighter from the outside to lend a new perspective.
That's exactly what Crazy 88 BJJ in Elkridge did when it was paid a visit from Kru Jose Villarisco, a former fighter who is an expert in Muay Thai kickboxing. Villarisco last competed in 2009 but according to the news release above, Crazy 88 BJJ head instructor Julius Park said each visit by Villarisco has led to a noticeable bump in skill by his fighters.
One of the biggest enemies of MMA fighters is complacency. It's very easy to start going through the motions if you're working with the same people over and over and over again and really not trying to learn anything new. Bringing in a fresh perspective, a new set of eyes, some outside opinions is a great way to change things up and keep your skills sharp.
