About Me

Hi! I’m Mr America Jason Kozma. Yes, for real. I’m LA’s top body transformation expert for over 20 years. I’m not the same thing as other “trainers” like you’ll find at big box gyms, or your friend’s trainer, or any other pretender.

I also have an elite squad of LA’s best personal trainers working for me. You can opt for training with one of them at about half my personal rate. Areas covered include gyms in Marina del Rey, Venice, El Segundo, Manhattan Beach, Beverly Hills, West Hollywood, Hollywood, North Hollywood, Studio City, Pasadena and Woodland Hills.

We also offer in home training in most areas of Los Angeles.

Note about availability - the time available listed on my profile only apply to me personally. Team trainers are available from 6am-7pm weekdays and 7am-12pm saturdays.

In my profile here is a very small sample of my many amazing client before and after transformations.

My background:

I’ve been lifting weights and bodybuilding since the age of 12, and competed in my first bodybuilding contest at the age of 15. I always saw bodybuilding competition as the natural competitive extension of the training in the gym. Ever since I learned that there was such a thing as a personal trainer, that was what I wanted to be.

Upon graduating college, I moved out to Los Angeles to chase my dream. Things happened, it was bumpy and tough but I eventually became very successful as a personal trainer, even adding a team of trainers working under me to handle the overflow of clients that I couldn't train myself.

I even got back into bodybuilding competition from 2003-2007 and won my weight class at the Mr. America in 2004 and Mr. Muscle Beach in 2007, accomplishing some of my long-held goals. My background in bodybuilding competition and my experience as a karate teacher combined well in enabling me to teach and train people from all walks of life in all the aspects necessary to transform their bodies in minimum time with maximum safety. I believe a great trainer has to be a great teacher.

What to Expect

What to expect when you train with us:

Client Success Story

Jason is the real deal ... it's no joke that he can truly transform your body and make the most of what you've got.

The first time I worked with him, he whipped me into amazing shape in eight weeks! He works with you to develop a workout and nutritional plan and makes sure you stick with it! There is no cheating with him because for some strange reason, he'll know if you have. He's a great motivational fitness trainer, and if you want hardcore results, Jason's your man.

I'd recommend him for anyone serious about body transformation.

-- Marites

Training with Jason Kozma has been a real learning experience.

When I started my 8 week fitness/nutritional plan with him, I was "skinny-fat" I only ate a real meal once or twice a day and never lifted weights. He taught me how and what to eat and how to sculpt my body. I weigh exactly the same as when I started but lost fat and gained muscle.

I went from 18% body fat to 13% Jason always made the workouts fun but effective.
I highly recommend him 5 stars!

--Kate

Training with Jason Kozma will be the best money you'll ever invest in yourself. Jason will analyze your weight, bodyfat, and measurements to create a custom meal plan and exercise program based on your fitness goals. While training if he sees that you need an adjustment to your meal plan he will do so. Show up focused, do what he says, eat what he says, and you will get the results you want.

In March 2018 I reached a wall in current meal prep and fitness plan. I just couldn't lose the weight I wanted to before my sister's Bachelorette in June! Desperate, I turned to Jason, who I wanted to train with for years. I followed his meal plan 87% of the time, worked out with him as instructed 3 times a week, and worked out on my own about 2-3 times a week. From March 25, 2018 to June 15, 2018 I lost 18.5 lbs and 10% body fat!!! I will continue to train with Jason to decrease body fat and gain muscle. Can't wait to post more results in the next coming months!!!

Contact Jason for a body transformation! He is the best! You won't regret it!!!

--Celeste

I've been working out with Jason for two years now, and I couldn't be more pleased with my results. When I wanted to get skinny, he got me skinny. When I wanted to get muscular, he got me muscular. And, on top of that, I genuinely enjoy working out with him. He's a pleasure to be around and makes me look forward to my training days. I could not recommend him more!

To say that Jason is an incredible personal trainer is an understatement. He takes you through your personal journey of what you want to achieve and helps you do it. Not tomorrow, not next week, but today. He personalizes each workout to fit you and gives you a nutrition plan that fits you as well. If you want results, go to Jason. You won’t be disappointed.

Jason is a top expert and highly respected in the fitness industry. Jason Kozma is not just a body transformation expert and the best personal trainer in Los Angeles, he is a miracle worker.

Jason, When I first came to you, I was unhealthy: smoking, not eating properly, etc. didn't know how to work out correctly. You inspired me through my training to change a lot of things in my life for the better: i.e. quit smoking with-in the first week with you (a 20 year habit) and did not smoke at all after that, start eating right, making better choices overall. You know what I mean. How important you were in my life how your techniques motivated me, basically, through your expertise & vast knowledge how you taught me to truly change my life. I’m so happy because of that.

You truly know how much you changed my life. I never imagined I could transform my body, my health and my self-image.

Thank you so much Jason for all your expert help!

P.S.: I should point out that when I met you I was trying unsuccessfully to lose weight on a 1000 calorie a day diet. While training with you for my first NPC bikini contest we had me losing fat while eating 2641 calories a day at 5 weeks out! We had gone from 22% body fat at the beginning to 13% at that point, to 10% on show day. Amazing!

I trained with Jason for over 3 years. During those years I have never felt or looked better. As I have gotten older, the importance of living a healthy lifestyle has dramatically increased. The demands of work make the process even more difficult. However, Jason manages to find a program that works with anyone's schedule no matter how demanding. Besides organizing the very best workouts for me, he also organized a diet plan and followed up diligently to make adjustments to ensure I met my goals. Anyone who is serious about being healthy, feeling good and looking great should call Jason. My only regret today is that I have moved to China for work and I can not convince Jason to follow suit to continue training me.

It is a hard thing to find a personal trainer who is both knowledgeable and professional when it comes to women. Especially women in my category - over 50. What a difference I can see in my body! He has also given me some tips on how to improve the inner workings of my body. I have found a rare find in Jason.

Jason is the best personal trainer out there. His knowledge of the body, his adherence to proper form and technique and his strong emphasis on diet combine to help you get noticeable results quickly. Whether you want to gain muscle size, increase definition or drop the pounds, Jason is the trainer you want. He's not the kind of trainer that stands there, counts out 10 reps and then tells you you've done a good job.
He will push you hard, motivate you and get you to levels of fitness you never thought possible. And after all, isn't that what you want?

Jason and his team are amazing. I got in shape fast and felt healthier in a very short time. The plan was laid out, all I had to do was show up, worth every penny! Thanks guys :)

I read that Jason was one of the best trainers out there and definitely he is. He gave me an appropriate nutritional menu plan and it works. He motivates me to push past my perceived limits to get a result. Every workout is intense but every workout is also different. He utilized free weights as well as weighted machines to build my strengths. I have incredible energy, my balance and flexibility have improved immensely. His goal is clearly to get his clients as healthy and fit as possible. I highly recommend him!!!

Jason has proven to be dedicated to the success of his clients through his very specific nutrition plans, and training programs. I have seen my own body transformation, significant decrease in body fat %, and muscle gains! I highly recommend him to anyone looking for serious results. Discipline and hard work required!

There's a reason why Jason Kozma is consistently ranked as one of the top personal trainers in Southern California. He gets results in a meaningful, sustainable way. I started training with him when I noticed my 6-pack abs were looking more like a beer keg and I kept having to buy larger sized clothes. It was difficult for me to look at myself in the mirror and feel confident. I wanted to change my lifestyle and kick up my workouts. Jason more than delivered. Of course, I had to make the effort, but it was so worth it. I feel great, my clothes fit and I can see my abs again. Thanks, Jason! You ROCK!

When I was 53, I won the Venice Beach body building contest master's division because of Jason. I am a nurse by profession, not some disciplined, driven athlete.
His heartfelt encouragement gave me the courage and his training techniques, that were quite frankly not that difficult, gave me THE body! If you do what he says, you will get what you want - plus! Jason really cares about results for you, not so common in the training world I have found.
Don't put it off, it is never too late to win the body battle, and with Jason's help it will happen sooner than you think!
