My 50th birthday was fast approaching and I wanted to loose 10# of fat and gain 5# of muscle. I had zero experience with doing something like this so I asked Jason for some help. He was awesome! He met me the same day I reached out to him, put together a program for me, connected me with dexa scan to track progress, mentored me on nutrition and followed up to keep me motivated. Jason was super responsive and professional and knew just what I needed to do. 44 days later, Dexa confirmed that I lost 10.2# of fat and gained 5.8# of muscle following Jasons guidance! Thank You Jason!!!

Update as of 4/2.. (about 75 days into the program)
Lost 15 lbs of fat and gained 10# of muscle..
Dexa Results attached!…

Jasons program and advice got me the results I was looking for and then some!

Mr. Kahn's expertise and efficacious approach to exercise makes me never want to be without him. I have been under the tutelage and care of Mr. Kahn for three months; one hour, twice a week. I would have never set foot in a gym before. Now I look forward to every session. I am stronger and healthier with more muscle definition and a calmer disposition. His years of experience make me confident in his discernment. I am learning proper form and technique with the outcome being objective results and goal achievement. He has designed a curriculum to address my personal health and fitness goals. He is culturally aware and takes every aspect of who I am as a person into account. He updates what we are working on as he notices changes in my performance and strength. He asses my capabilities and adapts the program to challenge my growth in both strength and my belief in myself and what I can accomplish. Plus, he is just a great time! fun to be around, and actually knows what he is doing. Thank you!

Jason’s a fantastic trainer. I started working out with him 6 months ago as I was recovering from an injury and looking for someone experienced in strength and conditioning to help me get back into shape. Jason plans progressive programs with my goals in mind and teaches correct form so I can keep improving and not get hurt. I appreciate how he assesses where I’m at and designs programs to get me where I want to be. He’s super knowledgeable and easy to work with. Since working out with Jason, I’ve also changed my activity level and eating habits, and have lost 20lbs. I’m stronger, my clothes fit better, and friends keep telling me how great I look. Thank you, Jason!

Working with Jason has been a fantastic experience. As a woman who used to be incredibly intimidated by going to the gym, Jason has given me the tools to feel confident working out and I’ll be forever grateful for that! He breaks things down in a really easy to understand way and is happy to answer any and all questions, you can tell that he wants you to understand the “why” of what you’re doing. He really takes the time to understand your personal fitness goals and physical needs, and is truly so knowledgable. His positivity and encouragement are infectious and incredibly motivating. He has truly changed my relationship with working out - if you’re looking to gain experience or level up your workouts, Jason is the best choice you can make.

It’s my first time going to the gym in El Segundo and I feel lucky to have found Jason as my personal trainer. He is very knowledgeable and explains why and what we’re doing and also takes time to teach me how to do the exercises on my own. I feel stronger than ever, gaining a healthy weight and see the muscles to show more, love it!

I’ve known Jason for a few years now. We trained together for two years and then I moved further south from his location. I have to say that he is one of the BEST trainers that I have ever experienced. Ever. What can I say about him? What makes him stand out amongst all the other trainers? Several things...

First, he’s knowledgeable. He actually spends his free time staying current on fat loss and muscle hypertrophy research. Better than that, he shares his knowledge with his clients! If you’re the type of person who wants to enter the gym and do what you’re told, you can do that and you’ll be happy. BUT if you’re like me and you want to know the WHYs of what you’re doing, Jason encourages that! He wants his clients to be full participants in their progress, on every level.

Second, FORM IS KEY! He will make sure that each and every exercise is done with proper form and he’ll stop you if he sees form breaking down. Why is this important? Well, we’re all training to look and feel better. I’m a 42 year old mom of 2. I don’t have time for injuries in my life. I want results that are SAFE! Jason is a stickler for form and mastery. This doesn’t mean you’ll be working with 2lb weights everyday. This means that you’ll progress in weights and reps and overall time under tension at a rate that is safe and specific to YOU. And that will keep you getting leaner and stronger for a long time to come. As a former athlete, it’s so important to have someone that judges me to keep all of this in perspective.

Lastly, he walks the walk. He looks AMAZING! That should be a no-brainer but unfortunately there are trainers that haven’t mastered their own fat loss and physique goals. I want to train with someone that takes their own physical health and goals seriously.

Ok, last point: He’s a nice guy. Not super gabby, so he won’t spend the entire session running his mouth. Instead, he’s a quiet and firm presence that will give you the reassurance that he knows what he’s doing and will get you where you need and want to be!

Love Jason. He is a trainer that emphasizes proper form, creating a solid foundation from which to build lasting results. His attention to detail, commitment to his clients, and wealth of knowledge from decades of experience are qualities I value most. Really chill guy and interesting guy, easy to talk to. Thanks for all the help over the years!

Update: I’m sooo happy with the results I have. For the first time in 15 years, I’m seeing muscle tone on my legs and my body is changing! Jason is soooo awesome. Highest standards and always on my side, remembering my goals to help me achieve them. Woo woo!

The short version: Yes, he gets results (and quickly I'm thrilled to add), yes he's the real deal, yes, it's money well spent and yes you'll be glad you did. And he's so supportive you won't even dread going to your sessions.

Long version:
I've had a lot of trainers in the past 10-15 years. Maybe 10? So I have a bit of context and perspective.
He's detail oriented - I've worked with him in a group training situation with multiple coaches, as well as privately and he is always the coach watching every subtle twitch and nuance of movement to get the maximum from it.
I love training with him one on one for the obvious benefits of having his full concern. He's super present and available.

He listens and seeks to understand me - my goals, concerns, questions quirks etc.

He is strict in terms of pushing limits, but never willing to risk injury or push without knowing what he's asking.

He's very committed to results. He has given me so much extra information outside our sessions to help me get results and boost my progress. Progress is his goal.

Continuing education - seems he is always off learning more.

He's fun and cool which is what I want when I am struggling at the gym.

You know how usually you walk into a gym and some trainer asks you your goals, daydreams while you reply and then tells you why your goals are unrealistic but stick with them anyway, as they give you the same program they give everyone else and try to sell you their protein powder? Jason is the antithesis of that guy.

For the last four years training with Jason one-on-one I noticed a vast improvement not only on physique, but also my health . This is coming from someone who has practically never stepped into a gym for the past 27 years resulting in poor weight management and eating habits. It was hard work at first, but nothing worthwhile is. The years of dedication have lead to not only losing 20 pounds, but also significant muscle gains that are here to stay.

The very unique thing about his training is that he stresses form and technique rather than just adding load indiscriminately and haphazardly. His meticulous management has lead to no injuries to this day, which I often see with other trainers that disregard putting "FORM FIRST" (which is Jason's motto) which results in lost gym time and never achieving their clients goals. My results are steady and consistent and with confidence I can say are here to stay permanently. JK PHYSICAL CULTURE has my strong recommendation. He will produce the results you want.

Trust me - you’ll get incredible MEASURABLE results in the process. Form first!

Jason Kahn is an excellent physical trainer. I trained with him throughout high school and I am now a Division 1 athlete. The instruction he provided helped me achieve my goals of playing volleyball at the collegiate level by helping me improve my form to prevent injury and increase my strength and athleticism. He designs a plan that helps you achieve your fitness goals and increase your abilities as an athlete. Every person is unique, but JK makes sure that your plan fits you as well as possible. Jason Kahn is definitely a 5+ star physical trainer.
