Hire Jason if you’re serious about making a change! He is a master of transformation. I’ve been working out for two decades, and he has brought me to a whole new level of fitness and strength.
Results oriented and has a food plan that is helpful if you stick to it!
Thanks Stephanie!
I've been working with Jason for 6 months on my diet and strength goals, and the results speak for themselves — I've lost 30 lbs of fat while gaining muscle. He put me on a high-protein diet with a consistent strength training routine, and I saw great results even without much cardio. My next goal is to drop another 20 lbs of fat and maintain 150 lbs. Highly recommend this program — just know that consistency is key to seeing results.
Thanks Dan!
I started training with Jason (THE Mr. America!) seven months ago, and it has been one of the best decisions I’ve made. Coming from a background in gymnastics, dance, pageantry, and modeling, I wanted to challenge myself by stepping into the world of bodybuilding. I had no idea what to expect from working with a personal trainer, but I knew I wanted someone who could not only help me reach my goals, but someone I could truly trust to get me there in the healthiest and most effective way possible. Just seven months later, I stepped on stage for my very first bodybuilding competition and placed! Jason was even kind enough to come to my show and cheer me on, which meant the world to me. Training with Jason feels like training with family. He genuinely cares about his athletes and always has our best interests at heart, both inside and outside the gym. We’re training to win, but we’re doing it the right way… with discipline, consistency, hard work, and no shortcuts. If you’re looking for a coach who is incredibly knowledgeable, supportive, and truly invested in your success, I can’t recommend Jason enough.

Jason was great at pairing me up fast with a phenomenal trainer that really helped me learn proper technique and form. Truly happy with the experience and great to work with!
I reached out to Jason Kozma about training, and he got back to me the same day, which I really appreciated. He quickly set me up with Brad, and Brad reached out almost immediately to get things started. Brad has been great. He’s knowledgeable, professional, and nice. We trained four times a week, and I noticed real improvements in my strength and endurance. Overall, a really positive experience.
I’m a senior citizen who has never enjoyed exercise—I’m one of those people who basically only exercises when I’m paying someone to hold me accountable. I only do it because I know it’s necessary for my health, not because I like it. I contacted Jason in August to try to find a personal trainer who would come to my location (my apartment has a decent gym) and train me and a friend 3x per week. I was also looking for nutritional guidance. Jason quickly put me in touch with one of his network of personal trainers, Brad Brisbin, and we had one trial session and hit it off well. Jason provided a nutrition program and weekly follow-up emails. Now to be honest, the nutrition program turned out to be more ambitious than I was ready to commit to, but that’s on me. The physical training however is going really well. Brad is friendly and knows his stuff, is well organized, punctual, & communicates clearly. He challenges us and at the same time he doesn’t push me too hard. I got a DEXA scan before we started and at the 6 month mark I’ve lost 13.2 pounds of fat and gained 4.6 pounds of muscle. So if you’re looking for a personal trainer plus nutrition program, I recommend contacting Jason. And if you need a trainer who will come to you in the LA area, ask him to put you in touch with Brad.
My husband and I worked with Jason in 2008 and had great results. When I needed to increase my fitness for tennis, I knew I wanted to work with Jason again. I signed up for the online program and I was very happy with the outcome. The nutrition program was customized to my goals, he helped me develop a workout schedule that fit into my life and I found the workouts in the app easy to follow. I highly recommend Jason and the online program!
I highly recommend Jason and his team! I completed the 16 week program with Sebastian and he really helped push me to get stronger and improve my mind-muscle connection. I am very satisfied with my results and I opted to extend the training further.
This is a fantastic training service. I love training with Nicholas. He really knows what he’s doing.
Thanks so much Joseph!
