I highly recommend Jason's training program. Following his diet and exercise plan I was able to see results in a short period of time. After 6 weeks I'm back to wearing my "skinny jeans" and couldn't be happier More...

Jason has a nice group of trainers who know how to push you without hurting you. Always on time and ready to train, my guy Jerry is enthusiastic and clearly aware of my physical limits and overall goals. It's a pleasure working with him. Burn fitness where they operate is a good gym. It's not fancy and could use some equipment upgrades, but for the price and location it works. More...

I've been working with Jason for two months, and started a program with him after hitting a plateau with my former exercise routine (mostly pilates, a bit of cardio) and not seeing results. In this time, I didn't have a lot to lose, but did end up losing ~6 lbs and 6% body fat. Better yet, my hips, waist, arms, and legs are all visibly more toned. I've worked with several trainers in the past, and none have given me the results I was looking for. I have a tendency to befriend my trainers and negotiate with them on days when I'm feeling tired or off. Jason doesn't let me do any of that (which sucks in the moment but is better for you in the long run!). He's strict about the exercises and generally knows what you can handle (but will adjust if you're in pain or really struggling), and also knows what exercises to avoid depending on your goals. I followed his meal plan 100% for about 3 weeks, then about 75-80% for the rest of the 5 weeks. Even with not being fully compliant, I still saw meaningful results. I look forward to continuing to work with Jason and to attaining even better results! More...

Alex is a great trainer. I am new to weight training, so I had to begin from the very basics. He is very patient and careful to details. He is very concerning about the right technique and safety of all exercises we perform. He also pays a lot of attention to flexibility during strength training. I was very bad at it in the beginning but after just a month of training 3 times a week my flexibility increased dramatically. I highly recommend him if you need really professional trainer who can come to your own home or apartment building gym. I believe he also can train in commercial gyms but we always train at the gym at my apartment building. Alex, thank you so much!! You're the best trainer in LA :) More...

Best trainer in LA! I've been working out with personal trainers since my very first workout 5 years ago. Since then I changed about 4-5 trainers and finally found the perfect one. We've been working together about a year and with him I began getting the real results I needed. We are working in my home gym which he helped me to build, suggesting the equipment I needed and choosing the right one. His workouts are simple but surprisingly effective. He is very much in details and knows exactly what I need to do to get what I want. I'm now in the absolutely best shape of my life, thanks to Alex. More...

Training with Jason has been one of the best decisions I've ever made.After discussing my goals he customized a plan tailored just for me and now, a month and a half in, not only can I see my body transforming but I also have much more energy in general. Don't get me wrong it is tough! Like supppper tough! He will definitely push you and you might even hate him just a little at times but its all to your benefit. Sticking to the meal plan has been the true test of commitment but if you can toughen up and stick it out I promise it will get easier! As long as you do your part Jason will help you get the results. More...

I was at a point in my life where I was tired of putting in the effort in the gym and not seeing commensurate results. As luck would have it, I ended up meeting Jason and immediately knew I wanted to train under his watchful eye. Over the course of 10 weeks, I went from 14% body fat to around 6% and looked better than I ever had. The next 10 weeks was spent bulking up and I put on 20 lbs. of pure muscle (if you don't believe me, check my before and after photos on his website). Jason's plan isn't for everyone. It takes a lot of hard work and determination, but the results are nothing short of phenomenal. I highly recommend Jason and his proven weight loss or muscle gaining system. More...

Wow, Where do I begin?! Jason Kozma has truly changed and transformed my life, my body, my health in so many positive ways! I am so thankful for him. Finding him has been one of my biggest Blessings. Here is my story which ultimately led me to meeting, Jason,  amazing trainer/transformer:My journey all started with a low thyroid condition combined with needing to take steroids for a related inflammatory health condition. As a result I had gained an extreme amount of weight. I had tried out different trainers in LA, some very expensive. Over a one year period my weight didn't even go down even 1 pound. Frustrated, I almost gave up, but then I came across Jason's website one day as I was searching for experts in weight loss. I decided to meet with him, and set up a consultation. In that one consult Jason blew me away with his immense scientific knowledge! He explained to me why I wasn't losing weight, despite all my work with those LA trainers. Jason laid out a complete program for me to follow that combined his pioneering weight training and work out techniques with specific supplements and a detailed nutrition program that was customized to my issues (thyroid, female hormone imbalance and age). He also gave my program all written up in a folder, including homework to send to him of my meals, etc (all included in his training fee!). Blown away! I am in the medical field myself, and I was surprised that he knew even more than the doctors I have been going to who didn't seem to have a clue on how to help me lose my weight or feel better.As I embarked on Jason's program, I began to have more energy. Friends told me I was starting to glow, and wanted to know my secret. Every week working with Jason,  I would lose weight on the scale, and by 6 weeks I lost 27 POUNDS with Jason!!!!!! Whoa, I am in complete shock! When other trainers I worked with over one full year couldn't make a difference, Jason helped me transform my body and my life within a short span of time! And I am happy to say I am continuing to make positive changes in my weight, my muscles, the way I carry myself and my energy. God Bless you Jason!It's a treat to work out with Jason as he is very serious about technique and posture. He is very attentive to my form when we work out, and is "no nonsense". Over time he has also been my confidante... a real life coach. I can say he truly cares about his clients. I looked up his credentials, and he has been a Mr. America himself with so much in-depth knowledge about the body, muscles, metabolism, hormones and physiology, and has helped so many clients not only feel healthier and strong, but also win their own fitness contests too! One day I would love to try for a contest with Jason's guidance.I normally don't write reviews but felt compelled to let everyone know about my journey in the hopes it may inspire someone else who thought there wasn't any hope. From someone who never wanted to get out of bed due to my health issues to someone who now has energy, who has shed so much weight, who loves her body now.... I am feeling so much better about myself and self esteem. Jason is truly a life changer, not just a trainer who works out people, but a true expert in healthy weight loss and helping one achieve a beautiful sculpted physique. I'm feeling so much sexier again, and this has translated to my work and interactions with people and dating life.I can't thank you enough Jason! God Bless you for all you have done for me! More...

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!!! More...

Jason and his team are the trainers to go to if you are serious about strengthening your body and losing weight. After back surgery and having 2 kids a few years ago, I had gained weight and lost both core strength and my back was very weak. Jason created an eating plan that resulted in me losing 14lbs in 8 weeks (simply by following the plan) and his colleague Brandon was able to significantly increase both my core and back strength. I feel and look so much better.  If you want a no-nonsense, result-orientated trainer, Jason is the guy to go to. More...

Jason Kozma is hands down the best trainer out there. I played Division 1 volleyball in college and then became a fitness instructor myself post-college, so I've experienced several different trainers throughout my athletic and personal life, but NONE compare to Jason. His programs actually work!!! His results speak for themselves - after just 8 weeks of training with Jason, I've dropped 12 pounds and lowered by body fat from 22% to 12%!!!!!!!! Even more importantly, I feel better than ever both mentally and physically. My daily energy level is at an all-time high due to his nutrition plan and I am leaner and stronger than I've ever been. He sincerely takes the time to understand your personal goals and develops a program for you that is hand-tailored to achieve those goals. He is extremely intelligent, experienced and knowledgable in the fields of body building, body sculpting and nutrition and thus has the ability to sculpt your body into the shape you desire. He is also very professional and respectful, has never missed a session and is always on-time. While you are training with Jason, he gives you his full attention to ensure that you are using the correct form during each exercise and motivate you to put in the work to achieve your best self. I truly feel like a new person since I started training with Jason. In a nutshell - JASON IS THE BEST! More...

I just finished a 12-week online program and am writing to second all of the good things that reviewers have said about Jason. My work schedule is pretty unpredictable, so I decided to go with the online training option. Jason designed a plan for me and every week I would send him in my diet and exercise logs. He would read these closely and email me back with feedback and suggestions. When Jason noticed that my legs were my weakest body part, he suggested that I come in for an in-person session to show me the ropes. We came up with a new plan for legs that produced immediate results, which makes me wonder how much more progress I would have made had I been able to schedule live training sessions with him. Anyway, after twelve weeks, I've lost 16 pounds and my body fat percentage has dropped from 14% to a little over 5%. The only thing I wanted when I decided to sign-up with Jason was results, and he was able to deliver. That's really the highest compliment that I can pay him. If you're serious about getting results, give Jason a call. More...

I started at 235 lbs, I lost 15 lbs in 2 months on the scale, I was able to lift more, and my energy levels increased dramatically. What sets Jason apart from other trainers is his dedication to helping you achieve your goals, by which I mean if you aren't achieving the improvements he is expecting each week, he'll sit down with you and go over every part of what you did in the previous week to figure out why the target was missed. I've worked with trainers who take your money and put you on a treadmill for 30 minutes, so to find a trainer who makes it his personal mission with weekly checks and followups to ensure you are making progress every week, was truly a refreshing experience and showed me the difference between an average trainer, and a great trainer.The other great thing about working with Jason and his team is that he gives you the tools to help yourself.
