Daily Riesgo
"Amazing work out with incredible instructors! I started training Muay Thai here a few months ago and the work out has been unlike any other. It’s fun, and very motivating to work with a 7x Muay Thai world champion."
Brandon Rocker
"I can’t say enough great things about Cosmo. He’s incredibly welcoming to complete beginners while also being an outstanding coach for experienced fighters—including helping UFC athletes during their training camps. He’s not only highly skilled but also a genuinely respectful, friendly, and humble person. Cosmo is a true warrior and a class act all around. I have nothing but respect for him."
Bailey Watkins
"Good Boy Family is the place to be training your fight skills in SWFL. Come try a class, you’ll see why we have teammates driving consistently from places like Sarasota. Coach Cosmo and Coach Christian mean business. The team is like a family. 👊🙏"
Cristhian Britez
"What better place to learn Muay Thai than with the 7x world champion Cosmo! Definitely the best place to learn Muay Thai. More than a gym, you feel like family. I went for the first time to try and my wife would only accompany me, and the whole training was so good, we both ended up signing up. It's incredible! What stands out the most is that Cosmo and Lari are super professional and humble. They teach with patience and those of us who are starting out do not feel different, since they treat us all the same and the people with more experience teach those of us who are starting out. I am very grateful for the opportunity and I recommend 100% to everyone!"
