About this pro

My name is Jay and I'm the Muay Thai striking coach at 303 training center. Home of Rose Namajunas and Pat Barry! My wife, Jamie (assistant coach/kids coach), and I have combined our collective 15 years of martial arts and fitness experience to make it easy for anyone to start their journey on the long road of martial arts! I am undefeated in MMA at 7-0, 4-2 in Muay Thai and am currently still fighting. My wife has had one Muay Thai fight and has competed in several Jiu Jitsu tournaments. We have developed a system that allows beginners and fighters alike to better themselves with full routines and curriculums for fitness, yoga, meditation and martial arts. Let us know if you're interested in kid's classes! We also help with fight camps and weight cutting. Intimidated with big gyms? Call us, we’ll get you ready first! 

**ISSA PT Certified**

The greatest gift one could give another is the knowledge to care for (and protect) the mind and body.

    Where to start! Jay and Jamie are not only amazing trainers but also amazing people. My wife and I have worked with Shutupandtrain for almost a year now and I have to say both my stand up and ground have benefited from it so much! Jason's level of commitment to the sport really comes through in his coaching, I'm in the best shape of my life! Faster, stronger, fitter (even though I'm only getting in 1 run a week, sorry Jason haha) and my technique has come a long long way! They will help you set goals for any level and ensure your on the right track at all times, whether you want to lose weight, build muscle, learn Muay Thai or BJJ, shutupandtrain will help you get it done!

    I like how Jason gave me the oprotunity and the tools necessary to focus on my goals and the push I needed to follow through and accomplish them. The work was always tough but the results were amazing. I would recommend him to anybody looking to get to that next step in their training and in their personal life. 10/10 would do again.
