Overall awesome facility and staff!

I needed to do a product shoot for a brand I am working with and after every other gym in the area ignoring me or telling me "no", Triton said Yes!

Upon visiting the gym for the first time, I was impressed with the facility and everything they had to offer. Indoors they have a wide variety of MMA gear and 2 large mats with plenty of space to train. Outside, the terf/ grass was a nice open space with a variety of cross fit gear. They also have weight lifting gear i.e. benches, racks, plenty of weights (dumbbells, barbells, plates, etc.) which is all well taken care of. Overall, I liked the atmosphere of the gym. No egos, just friendly staff and members there to get a good workout in! I would highly recommend checking out Triton!

The best gym I have ever been a part of! 
Theres an awesome space for outdoor weight training, an open turf area, and space inside for classes (pre-covid times). 

The instructors are so knowledgeable and helpful too. Since joining John Marsh has built up my strength, endurance, and confidence more than I could have imagined, but the community here has to be the best thing. I've made so many great friends and memories inside and outside of the gym. I highly recommend checking out Triton gym if you haven't already!

I absolutely LOVE this place! I may have ended up here by chance (my previous gym merged with Triton back in 2019), but I could not be happier. It is very no frills, but the workouts are amazing and they have a variety of equipment for all types of exercise. I really love the HIIT and weight lifting classes, and for those interested, they offer a lot of kickboxing/MMA classes as well. The trainers are all very approachable, knowledgeable, willing to work with you to achieve your goals, and work around any injuries you have. They are creative and provide real time feedback on form/technique, but make sure to challenge you to max capacity. Triton really kicked my butt into shape and I am proud of how far I've come with their help.

Triton is sooo much more than a gym though, it is a community and a family. Everyone cares about one another and I consider so many people there to be close friends. This place is a South Bay gem and what's better than working out in the sun with your friends?

I can't say enough amazing things about this gym. After one free trial class, I was hooked. I love the class variety (I go to HIIT, Kickboxing, & Weight Training),  the variety in class schedules, but mostly the sense of community. I have been attending classes for about a year now, and can see my progress improve thanks to the hands on instructors that always go above and beyond. The other gym-goers have become great friends outside of the gym and I always leave feeling challenged. The owner John is the perfect combination of encouraging and pushing, and one of the nicest guys you will ever meet.  I genuinely wake up every morning excited to go to the gym and see what that day's class has in store.

Wow! What a terrific gym. Great culture, great energy. Fitness blended with martial arts provided the perfect format to motivate my two teenagers to get a great workout. Rob was welcoming and incredibly talented!
