“I started training boxing with Coach Marcos because he has the same aggressive style I have — always moving forward, with the ‘eye of the tiger.’ On top of that, he has excellent technique and is a true role model as a human being. God allowed me to witness the great work He has done in Marcos’ life, both as an athlete and in his spiritual journey. He is an example of character inside and outside the ring, and that’s why I chose to train with him.”

"I’m from Taiwan and have been learning boxing for five years. When I travel, I often look for places to train because I want to keep up with my boxing practice — that’s how I found Boxing Laboratory on Google Maps.
At the time, I had just started learning Japanese, so I communicated with the coach using a mix of English, Japanese, and body language.
The one-hour training session was intense and well-structured. The coach carefully corrected my posture and helped me fix some misconceptions I had — it was incredibly helpful!
On top of that, the class was very affordable — truly great value for the price (laughs).
If I get the chance in the future, I’d definitely love to train there with the coach again!"

"I’m a 48-year-old man. It’s been about a year and a half since I joined Boxing Laboratory. At first, I trained at another boxing gym, but there I was constantly beaten by younger members, and some even mocked me. During that time, I spoke with an acquaintance who introduced me to Coach Marcos.At first, I thought he looked very serious and even a little intimidating, but I soon realized he is an extremely kind and attentive person, who teaches with great care and dedication.He guided me to train the fundamentals rigorously. About a month after I started training with Coach Marcos, something amazing happened: members from the other gym began telling me things like, “Wow, your punches are so much sharper,” or “Your stance looks perfect.”Today, I can spar on equal footing with the younger members, and that’s thanks to his method. I’m deeply grateful. I can say with confidence that Coach Marcos’ training delivers real, concrete results.Another impressive point is that people from different countries, regardless of nationality, come to take his classes. For those who hesitate to start boxing because of age, here’s my invitation: come train with us at Boxing Laboratory. The results are guaranteed!"

“I used to be an MMA fighter and have trained a lot. When I started training with Marcos at Boxing Laboratory we quickly built a great teacher/student relationship.
Marcos is a professional and a great teacher. Whether you’re at a pro level or just starting, Marcos will treat you the same and make sure you learn and progress in your martial arts journey.”
