MEET OUR TEAM

Michael Cantu
GymGuyz San Diego OWNER
After college I spent 10 years on active duty in the United States Marine Corps fighting in both Iraq and Afghanistan. Getting out in 2013, I joined corporate America working in multiple sales roles in industrial distribution and manufacturing. Decided to become more involved in local community and business and opened GYMGUYZ San Diego in 2023.
I have played sports my entire life and being a Marine is a very active profession. After my service, physical fitness became less active in my life and the need to have it more a focal point in our lives was a major factor in choosing to open GYMGUYZ. Fitness being so important for overall health and longevity was a very attractive part of GYMGUYZ!
Our contribution to the local community and our ability to have a positive impact on our clients’ lives. A more fit community is a more healthy community. All we can do to help in that process is important.

My goal as a trainer is to educate, support, and motivate you to achieve your goals in a healthy manner by designing a custom program that is fun, challenging and sustainable.
Everyone’s fitness journey is different. You should enjoy it! I want to make fitness and health a lifestyle for you and allow you to find that balance. We will work together to help you become the best version of yourself inside and out.

I have been working out for 15 years, initially as a way of gaining confidence and competence with my body and turning into a foundation of my life to feel and perform my best. I have participated in many activities including wrestling, Brazilian jiu-jitsu, rock climbing, backpacking, archery, and was in the Army as an infantryman where I sustained a serious back injury which was my biggest personal challenge to overcome.
I focus on functional training with the goal of moving better, getting stronger and living longer!
