Welcome to FightBuilt, our proprietary Strength & Conditioning (S & C) program at our San Diego gym. Our Coaches designed it for the specific needs of our athletes and those who want to train like them. It incorporates functional fitness classes that make both our students and competitive athletes agile, conditioned, fast and strong.

We utilize numerous training methodologies, whether functional movement patterns or sports specific, to get you to where you want to be as rapidly as possible. We also provide specific dietary assistance and weight cutting strategies if desired.

Developed by some of the best Sports and Strength coaches in San Diego, our FightBuilt classes will get you in shape fast. We base these classes on the same training we use for our own athletes, so you know what we teach works.

We use fundamental movements as a base while incorporating sports specific exercises. In our group classes, students build a strong foundation and are constantly striving to maintain correct form and posture. This minimizes potential risk from injuries while maximizing exercise benefit.

Fitness is a huge part of virtually any sport, which is why we also offer private training in our San Diego Strength & Conditioning program. Our private training sessions are intense and exhilarating. We can design customized training plans specifically geared to you and your training / competition plans, whatever your sport.

Whether your goals are increased speed, strength, power or endurance, we use the exact same proven methods we’ve created for our own athletes that have allowed them to succeed at high levels of Amateur and Professional competition. If desired, we can also provide specific weight loss strategies and dietary assistance including proper use of nutraceuticals.

We conduct our training in a custom-built facility equipped for every aspect of Functional Fitness and Combat Sports training. Our equipment includes a large rack system, lifting platforms, bumper plates, barbells, dumbbells, kettlebells, heavy balls, med balls, strength bands, battle and climbing ropes, chains, plyo boxes, tires, hammers and more.

We also frequently take our athletes off-site to conduct a variety of training activities, including swimming, jogging, sprint work, etc. These locations include local universities, as well as natural facilities such as beaches and parks.

S & C: ERIC S.

It’s a group environment pushing you and being very motivating. I just get a way better workout experience and feel better about myself and my body. You definitely have to push yourself because in the group setting, you want to either be in the pack or above the pack. So that’s what I strive for. When I came here I was definitely the youngest person and I didn’t know anyone. They all introduced themselves and they’ll give you congratulations if you do really well or if you’re working hard.


I’ve been training most of my life. I grew up in a Martial Arts family. I played college football. I’m getting a little bit older now with injuries. Accumulation over the years with training Martial Arts and Jiu Jitsu. Plus I’m a restaurant manager so I can’t have my face dinged up, as I work in the industry. For me, what’s great about The Arena is the Strength & Conditioning classes, the heavy lifting, as well as the advice I can get on dietary needs or just anything I have questions with in overall training.
