before and after Aaron - Los Angeles personal training

Q: Why is Jason Kozma’s High Performance Personal Training program more effective than other personal trainer or gym’s fitness programs?

A: My program is a results – oriented program. It focuses on how you look in combination with your health, strength and well-being. Most fitness programs emphasize improvement in athletic fitness and strength, hoping this will create the desired body shape. More often than not, it doesn’t: you end up with oddly developed or an unchanged body and an unhappy client.

My program is designed to reshape your body. You will gain strength, be healthier, and more fit.  Together we will create the body you want.

before and after Julie - Los Angeles personal training

Q: What’s the difference between Jason Kozma’s High Performance Personal Training program and what other trainers provide?

A: 1. Most trainers train clients the same way they train themselves or all of their clients without any thought given to the uniqueness of the client’s body. Their thinking is “If it works for me, it’ll work for you.” Unfortunately, most trainers have been training for many years and do not know how to teach a client how to get in touch with their body and feel their muscles perform the exercises properly. For you to shape your body, you must be able to feel and control your muscles. This is called the mind-body connection. I can teach you this.

2: Most fitness trainers have their clients perform the same workout every time, over and over again, for months or even years. My clients enjoy an ever- evolving workout that varies as their bodies and needs change. I see the body as ever changing. My instruction is not constrained by a certain rote series of sets, reps, and exercises. My clients improve quickly and safely.

Q: Why should I do his Los Angeles personal training program?

A: Results! Time and time again I successfully transform the bodies, minds and lives of my clients. Check out my before and after photos and client testimonials sections and see what you think – If I can do it for these clients – whether it’s 5 or 50+ pounds, I can do it for you!

About my programs: My programs combine weight training, cardiovascular exercise and a nutritional regimen. You can transform the shape of your body and dramatically improve your health, strength, and self-image. These techniques and my guidance enable my clients to lose (or gain), as the case may be) an average of 20 pounds in 8 weeks. 100% of my clients have lost weight (or gained muscle) after following my program within the first two weeks. Whether you are an advanced trainee or you have never stepped into a gym before, I can develop a program for you to get you to the next level of performance!

Even if you’ve never had success losing fat or gaining muscle before, my individually tailored program will work for you! Call now and find out how quickly you can get in the best shape of your life with the best personal trainer in Los Angeles – Don’t you deserve it?

over 35 bikini body
Being physically active and in shape has always been a part of my life. Building and maintaining a beautifully shaped and well-toned body requires dedication to a regimen of cardiovascular exercise and weight training; along with compliance to a healthy diet. I began to find my workouts not only become boring and mundane, but I found myself having to work harder in order to achieve the same goals. It was becoming tougher to stay in shape and I wasn't progressing in my training. For the first time, I decided to seek out a personal trainer. Given I had always trained myself with good results my criteria for a trainer was strict and the shoes looked like they were going to be very difficult to fill! I was very surprised and pleased when I found Jason. Jason takes pride in every client he personally trains. He's fully vested in your success and pushes even the most avid and knowledgeable fitness buff to levels they thought were unattainable. His many years of experience and vast knowledge enables him to put together a personalized program. He balances the right amount of weight training, cardio exercise, supplement use and diet; tailored to meet the needs of each individual client. My workouts with Jason have allowed me to maintain my physique by working out smarter and more effectively; every rep counts. No time or energy is wasted. Even if you're a serious athlete or long term fitness advocate who has trained on their own for years, a workout with Jason will most definitely be challenging, yet rewarding. My results are no longer just good, they're great.....thanks Jason!! Roxanne over 35 Bikini Body

Jason Kozma is not for everyone. My experience with Jason is that he is all about results, and those results are achieved in direct relation to a client’s level of commitment. Jason utilizes both state-of-the-art training techniques as well as equally effective dietary guidelines, with both disciplines required for total body fitness and good health. Following an illness and major surgery in January of ’12, I went from 178 lbs. to 149 lbs.. and for 6 mo’s tried everything I could think of to put back muscle and weight, with little result. Then I started personal training with Jason, who radically changed my diet, with all healthy foods and supplements devoid of side effects, along with a strenuous 3-days per week training regimen, and I’m back up to 164 lbs. (and still gaining) with muscle accounting for all the added weight. BTW, I’m 77. With total commitment and the right trainer, it is NEVER too late!! David, Brentwood

Dear Jason, When my neighbor Paulette recommended you as her personal trainer, I was turned off by my previous experience with a trainer I had in the recent past. She had thin legs and had me do her own workout consisting of thigh building exercises which were only further thickening my legs. Your no - nonsense approach to improving my body was just what I needed. No more bulking exercises, but a unique workout designed to suit my body. My husband has been one of your strongest supporters, because he has seen the way you have sculpted my body for the better. Jason, you are an artist when it comes to sculpting bodies, both male and female. You customize the workout to the clients needs and manage to keep it fun and interesting. I would highly recommend you to anyone who is serious about starting a workout program where results are inevitable. With much appreciation, Delaney; Mother, Gourmet chef over 50 body transformation

4 years living in hotels, working way too hard and working out way too little had resulted in what I thought was an extra 10 – 15 pounds that I just couldn’t get rid of no matter what I tried. When someone enquired when I was due I realized it was time to really do something about it. Jason Kozma was the answer. In 8 weeks Jason gave me a better body than I had ever had before. 10 – 15 pounds turned out to be 25 pounds and the six pack I had only ever fantasized about became a reality. Jason’s combination of weight training and his amazing diet (he actually had me eating 3 times as much as usual and dropping pounds by the day) is the quickest, healthiest way I know of to guarantee the body you’ve always wanted. The effects of training with Jason and the new body that came with it have enhanced every aspect of my life…I can’t recommend him highly enough. Not to mention he has you laughing the whole way through it. Kym Wilson red carpet ready

I always look forward to my training sessions with Jason. No matter how I feel when I enter the gym, I always have a great workout and leave feeling great. Jason has helped me to become bigger and stronger than I ever thought possible. I had found it extremely difficult to gain muscle mass, but Jason seems to be able to push me that extra bit that I needed to get the results I was looking for. Jason has always been very professional in every conceivable way: his knowledge, punctuality, attention to detail, and his ability to develop my weak areas. Jason always keeps up with the latest news in nutrition and supplements, and has always made his program work for me. Steven Buscemi; Entrepreneur (not the actor) Steven got ripped
