Some Yelp Reviews

  Jason is fantastic! I've utilized Jason's diet plans twice. The first,  to lose pregnancy weight, which I was able to do within 3 months. The second was to lose weight... read more I gained during the pandemic. I surpassed my goal weight within 6 weeks. Will continue to use Jason in the future to continue to build more muscle. If you follow his meal plan and exercise program it will work. Jason is very responsive via email and the workout app. I highly recommend him and his program!

  Jason, David and Mike at LA Private Trainers in Venice are amazing! The one on one training along with their knowledge and expertise in health and well-being are amazing. I... read more have shrunk my waist 2 inches and feel great!
Non-pretentious gym, state of art equipment, parking, safe, good vibe! Call Jason 310-721-4095 to book a session! What are you waiting for? Just do it!

  Jason Kozma is a diligent and motivating trainer with a team of excellent trainers on his roster! I lost 25 pounds in three months (three dress sizes, four pant sizes,... read more & one bra size) and am the strongest I've ever been. Jason set me up on a nutrition plan that was difficult at first but became routine. He paired me for weight training with Jerry, who has become like family. I'm still going three days a week to train and doing more cardio than I did in my teens and twenties. I cannot recommend Jason and his team enough!

  I've been working out with Jason for over 16 years now. He keeps me looking and feeling my best. I highly recommend giving him a try,(you'll be glad you did).... read more Not only does he provide fitness training, he also adjusts my diet as we go along. Absolutely the best trainer around!

  I hired Jason and Los Angeles Personal Training to help me get stronger (and fit in my old pants) after having two babies.  Jason was super responsive and professional.  He... read more asked what my goals were and talked me through the process and sent the information in writing as well.  He provided an 8-week postpartum diet, cardio, and strength plan.  It allowed for modifications as a breastfeeding mother and was very doable, though it required a lot of dedication as expected.  I worked with personal trainer Dennis who is very knowledgeable, prompt, and flexible with training times.  They are both bodybuilders and are very knowledgeable about diet and fitness, including knowledge beyond just heavy lifting.  I am fitter and stronger than I was before having both babies and they have refreshed my dietary habits such that I have been able to maintain my weight during the holidays with ease.  Hire Jason!

  It's been a great experience training over the past 3 months. Jason provided a detailed nutrition plan at the start and Dennis has been an excellent trainer. They both have... read more bodybuilding experience so they know better than anyone how to transform your body. I've lost weight AND have been lifting heavier weights in their program so I can definitely vouch for them.

  Jason is really great to work with. If you follow his instructions-you will see results. Workouts and diet, supplements, check-ins, food lists, recipes, stretching...all the information and guidance is there... read more for you. Easy to communicate with him and extremely knowledgeable. He also has a great network of trainers across LA if you need someone neighborhood specific. I would highly recommend if you are serious about changing your body and want results.

  Jason Kozma is a life changer.  I was fed up with different diets and exercise and knew I need a lifestyle overhaul. I was so ready. I researched for months... read more and was beyond impressed with Jason's results. From the moment I contacted Jason he was responsive (and continued to be throughout the program) and knowledgeable. He provided a comprehensive training manual and diet plan (I highly recommend the nutrition program in conjunction with the weight training for best results). He connected me with the most amazing trainer, Jerry, and Jason reviewed and provided feedback on my diet logs. The results have been incredible. My goal was to significantly decrease my body fat and with Jason and Jerry's help they set me up for success beyond what I thought was possible. I have learned important, healthy habits from them and equally as important the safest way to weight train. To top it off, it was so much fun to see the results I was motivated and committed to keep going. I cannot recommend Jason's program enough. Just make sure you follow strictly what he tells you to do for nutrition and training and I promise you that you will see results beyond what you could have imagined. Best investment in myself ever. If I could give 10 stars I would.

  I will always remember turning 55 because Jason encouraged me to press more weight than i thought i could - and he got me safely up to pressing 300 lbs... read more with my legs! He called his trainer friends in the gym over to witness my skinny little legs doing that! It is a memory i treasure - I was doing hundreds of Tibetan Buddhist prostrations at the time and my thighs were like steel.
i would never have dreamed such a feat was possible - that's Jason's magic, helping you go beyond what you ever imagined you could do.

  Amazing trainer with a great network of (also) stellar trainers. If you can train with him directly - awesome. If you can't, he will refer you to someone who is... read more also awesome. My 4 week program got me started on a real life-changing journey: major lessons learned on form/posture/intensity - things you CANNOT do on your own. Thank you, Jason!

  Before training with Jason, I was still no stranger to the gym. In fact leading up to our first session I was on a 6 day per week, disciplined schedule,... read more but for some reason never really saw the results that I was looking for. As an obvious ectomorph, I was never able to really bulk up and keep any gains that I would struggle so hard to get.

But in the first month of working with Jason, I was able to put on a solid 5 lb's of muscle while retaining a very low body fat % (~10%). He corrected my diet, corrected my form, and pointed out all the flaws in my workout program that were keeping me from realizing my goals (mostly over training, redundant exercises, and form tweaks).

It's been about 3 months now and I am 8 lb's up from day 1 and still at 10% BF.

He is an expert, no bullshit kind of trainer, that has no problem telling you when you are wasting time or just plain doing something wrong.

If you're looking for someone to coddle you and talk about your day, look elsewhere, but if you are serious about improving your physique, definitely worth it.

  Jason created a great nutrition plan
catered specifically to my body, that I lost 10 lbs in the first week. David was my trainer and was super friendly and very... read more knowledgeable about any questions I had. He guided me to sculpt the exact body I had expressed that I wanted. I recommend Jason Kozma and David Hughes as trainers if you want to see results, and you want to see them quick.

  I was needing motivation and finding Jason definitely did the trick!  He's the real deal and can design a fitness program for anyone.  He makes it fun and brings so... read more much passion and excitement to the process which can sometimes be intimidating.  He's encouraging without being pushy.  Based on my schedule and location he connected me with his co-trainer Tasha who's amazing.  She pushes me a little further each week but never too far.  She curates each session based on what I need that day.  She's in tune with her client, prompt, energetic, flexible and knowledgeable.  Thanks Jason!!

  I travel a lot for work so I do the online training program and have been pleased about it. My original goal was to actually gain weight first and he... read more has successfully helped me achieve that. The program allows for flexibility (gym access, alternative exercises) and much appreciate the online training tool to keep track of progress.

Diet plan is also flexible enough to accommodate dietary restrictions.

Jason is very responsive and absolutely give 5 stars to communication.

  Jason is a miracle worker. We did a consult with him for my 9 year old son and my son has been so inspired ever since. After trying many different... read more diets and nutritionists, it's finally Jason's program that's getting us the results we were hoping for. He is incredibly supportive and knowledgeable. He is also responsive and supports you through the process. My son is becoming more happy and confident everyday because of you. Thank you Jason

  Jason's a really great trainer. I do the virtual personal training program because I know form, I just don't have the knowledge to build my own plan. Jason's always been... read more very responsive whenever I have questions. He doesn't give you a cookie-cutter plan; I have a few physical limitations and my gym doesn't have the widest variety of equipment and he was very understanding and helped find the right exercise substitutions.

I found the diet plan really helpful because it's flexible enough where I can try different foods, but specific enough about how much and when to eat so I actually see results. Be clear with your goals and stick to what he says and you'll definitely be happy with where you are in just a few months.

  Excellent customer service and services are a great value. Highly recommended. There is no substitute for training with a professional who understands nutrition, diet, and how to tailor a workout... read more program to your individual needs.

  If you're looking for rapid transformation success Jason Kozma is the best personal trainer available! Very happy with the guidance, accountability, and humor he provided during our training time together.... read more He genuinely cares about getting his clients the best results possible. If you are not in the LA area he also has an excellent online personal training program. Highly recommend.

  I live in Chicago so I used Jason's online personal training. It was a great experience especially for the price. He would monitor my workouts each week and let me... read more know if I should be able to go heavier on an exercise based on everything else I was doing. He'd also review my recorded diet and tell me where to tweak things. He was also good about reminding me to update my weight and progress pics, and he'd adjust the workouts or diet based on that. He was honest about how much weight/muscle I should expect to gain and didn't try to make huge promises just to get business.

  Jason is the best personal trainer. He knows exactly how to increase muscle and strength. I've built up muscle so rapidly due to his program. He truly keeps you motivated... read more and continuously pushes you to give all your absolute effort. I highly recommend!
