Client Testimonials
“Working out with John has been the most valuable investment that I’ve made in my life. I’ve been working out for 25 years, but I didn’t realize I had so much to learn about the physical body.
Working IN has also been a huge concept that I never really thought of prior to working with John. My physical, mental, and emotional health have all improved. John is the best in the field. It’s an honor to work with him and be a part of this community."

Shelby M. - Lost 19lb in 4 months
Having John as my trainer was a comforting experience - he knows his stuff. If he told me to eat 10 cheeseburgers that day, I would have done it.
Having confidence in John's knowledge was powerful and allowed me to not be as stressed during the process. Additionally, his combination of workouts and nutrition allowed me to see successful and quick results.
Yes, this process was very challenging, but I wasn't eating tilapia and broccoli every day; I was able to live life for the most part. I have worked with John for a while now, and definitely plan on continuing to do so in the future.”
Riley L. - 7.5% to 3.5% body fat in 3 weeks
“John truly has a gift when it comes to exercise science and overall motivation as a coach. His passion for health, functionality and his client’s goals is truly felt.
I contacted him about Men’s Physique Contest Prep only 3 weeks before I had to step on stage, and without John's expertise and motivation, I truly believe I would not have placed 3rd in the competition.
I started at 179lbs at 7.5% body fat 19 days out from my competition. When I stepped on stage I was 171lbs and 3.5% body fat."
Taryn O. - Lost 3lb fat and gained 2lb muscle in 2 months
“I know what you’re thinking, “This girl looks like she knows what she’s doing in the gym!” I used to think that too, don’t get me wrong…and then I met John. Not only did he teach me so much more in the gym, but I was also taught the importance of a proper macro diet, and I gained knowledge in what a good supplement looks like.”
Ryan K. - Lost 28lb fat and gained 7lb muscle in 4 months
“John is the best trainer I’ve ever had. I have been competing in Physique competitions since 2013 and thought I was advancing my physique the best way possible. Boy, was I wrong about that. He made me into an athlete again.
John changed my philosophy on training and my entire outlook on life, that is what separates him from others. I encourage any person to hire John as a trainer. I wish I started sooner!”
Paige M. - Lost 10lb in 3 months
“I cannot say enough good things about working with John. He takes a holistic approach to coaching which makes the transition to a healthier lifestyle attainable. The way that he breaks down each pillar of wellness made the lifestyle changes gradual and lasting.
In so many ways, I am truly a changed woman. I crave movement and workouts. I crave fats, protein, and leafy greens. I allow myself to say no to give time to myself. I am a better wife, Realtor, friend, and family member. Everyone should work with John and learn what he has to teach - you could not make a better decision.”
Alan D. – 8% to 4% body fat in 3 months
“John is my guy. I won’t go to anyone else for advice on fitness and nutrition. Everything I know and practice in the gym (and kitchen) comes from him. He has helped me train and achieve goals of all different shapes and sizes and he is the first person I consult. 6/5 stars.”
Lauren W. - Lost 12lb in 3 months
“I went into this program thinking that I would simply lose weight, (and I did), but more importantly, I lost a LOT of baggage (emotional, mental, psychological) that I had been holding on to that I didn’t realize was keeping me from achieving my fitness goals. I had no idea how mindful I would become in how I look at my body, how I speak to myself, how I choose my foods and exercises for the day, and how important it is to have someone that believes, REALLY BELIEVES, in you and your abilities.
I encourage anyone on the fence about this to take the leap— wouldn’t you love to change your mindset, body comp, and feel better physically and mentally? Believe me, your future self will thank you!”
Spencer S. - Lost 15lb in 3 months
“John is an exquisite trainer. His knowledge on the human body and how to make it function properly is vast and ever-growing.
His energy and passion for what he does is contagious and will ignite that fire in your belly. Whether you're trying to lose weight, train for a bodybuilding competition, or just trying to make a couple positive changes in your lifestyle, John will get you there.”
Lisa O. - Online Client
“I've barely done any exercising at all since I found out 3 years ago that I have two completely degenerated discs in my lower back. I used to jog/walk and I also did Tae-kwon-do in my 40's, but I just couldn't get myself back into the habit.
The routine John put together was definitely a challenge for me at the start but by the end I was managing through it pretty well for an out of shape 52 year old... with no discs! My stress level was kept in check as well. I actually started to look forward to stretching and breathing each day and my back was better for it all. Looking forward to working more with John in the next online program!”
Bo B. - Lost 15lb in 3 months

Yvonne G. - Lost 5lb in 4 weeks
“My weight has stayed the same for the past 15 years (except during pregnancy), and I always thought that extra 5lb was here to stay as dieting is not my thing. So thank you John. A few small changes to the way we eat and that 5lbs fell off effortlessly. John's knowledge, enthusiasm and dedication have been a wonderful gift to our lives.”
Sue B.

Joe M. - Lost 15lb in 3 months
Deb M. - Lost 13lb and 4" off her waist in 2 months
“John made a huge difference in my life. While working with John, my Type 2 A1C went from 6.8 to 6.1. I started to gain muscle and flexibility and for a 61-year-old post menopause, I was thrilled with the changes. After exercising, we added a food plan to my program and I immediately lost 15 pounds.
The pounds continue to come off but more importantly, John has taught me more about nutrition than I have learned from other sources in my life. I miss John. He is motivating, kind, and encouraging. I have learned life skills from John that will keep me moving and living for a very long time. I am thankful for his guidance.”
Branden C. - Lost 30lb in 4 months
Susan E. - In person client
“John’s fitness programs are amazing. His workouts reflect his holistic approach to fitness, incorporating strength, cardio, and balance techniques for a full-body workout. His yoga philosophy adds clearing the mind and developing neuromuscular coordination to the mix. His attention to the individual is highly appreciated.”
Brock S. - Lost 103lb in 10 months
“I highly recommend John to those who are looking to improve their long term health. In just four months of training with John twice a week I lost 53lb, dropped my A1c from 8.9 to 5.4, and significantly increased my general fitness and energy levels. Now, after 10 months of training, I have lost 103lb and I feel like a new person!
I had never worked out at all before training with John, and now I am deadlifting 205lbs for sets of 15. I still have a long way to go on my path back to health, but I know that through John's fitness training and dietary advice, I will achieve my goals.”
Tessa J. - Lost 10lb in 3 months
“I recommend John to anyone looking to further their fitness goals. His program wasn't just a workout plan but a comprehensive training on how to eat, sleep, and practice mindfulness for a full mind + body approach to health and fitness.
​
​I could not have expected a more positive change in my life since competing in this challenge in both the gym and outside the gym. The tools and knowledge John has given have been a game changer and I highly recommend this challenge to everyone!”
Cedrick H. - Gained 16.5lb muscle and lost 1.5lb fat in 18 months

Lindsey B. - Online Client
“John is the best at what he does! I have never met a trainer that has as much knowledge about your body and diet. Give him your goals and he will help you achieve them. I would recommend him to everyone!”
Demaundray W. - Lost 27lb fat and gained 9lb muscle in 5 months
“When I came to John Kempf for personal training and nutrition I knew that I was in for a life changing experience. John went over and beyond all my expectations and was truly a life coach. A lot of trainers and coaches just bark at you and put you through vigorous workouts. On top of that, they give you a meal plan that's most likely not catered around your lifestyle.
The precision in everything this man did was revolutionary. I've had many coaches and mentors in my life on all levels of sports. John Kempf is the best coach I have ever had and I'm forever grateful for his teachings. Great knowledge from a great coach!”
Misha G. - In person and online client
“John is absolutely AMAZING!! Prior to working out with John I was very active, hit the gym, tried numerous trainers, etc. My drive was there, but the passion and guidance was not. John has been a game-changer! His drive, knowledge and never ending desire to make you the best whole person is unlike anything I have ever experienced.
From mind, body and self connection he is the real deal. This is not just a quick fix, more of a life altering experience you will not regret. If you are ready to take your life into your own hands and be the best version of you (on all levels) John has your back. And you'll like the results too. I have John to thank for a new found confidence."
Ollie M. - Lost 4lb fat and gained 6lb muscle in 3 months
“When I came to John for help I was in a low place with little to no self-esteem. I have Cystic Fibrosis so my lungs always have been and always will be an issue. My lifestyle was beyond poor and I was accepting my fate of bad health. Thank god I reached out to John.
​
John introduced me to stretching, proper form, high intensity interval training and good nutrition. After our training not only was I stronger, but I could touch my toes, run for miles and damn I felt like an athlete. The strangest part was my lungs improved drastically with no medication change.
​
The greatest compliment to my hard work and John's training was the last time I was hospitalized. A CF doctor took one step into my room and exclaimed, "Aren't you a sight for sore eyes!" Thank you John for all you have done for me."
Arielle R. - Online Client
“John treats everyone like they are his best friend and puts his whole heart into your progression. I felt so comfortable with him and we had a blast. I’ve had dramatic positive changes with my body, mind and spirit.”
Pat M. - In person client
“My oncologist recommended strength training during my treatment, and the universe aligned for me when I found John. I envisioned gym machine workouts, but instead John performed a thorough assessment and evaluation and designed a program specific to my goals, and to my strengths and weaknesses. It has been an unexpected blend of functional mobility, strength, stretching, breathing and nutrition. He provides the perfect level of feedback and encouragement, along with gentle accountability.
One of my goals was to be able to do a pull up again, I could not do a single one at the start. After less than 4 months I am now up to 9 pull ups in a row. Bottom line, John has been one of the best investments in myself I have ever made.”
Dyana P. - Online Client
“We made it warriors! I’m actually sad that it’s over, but this has made me definitely incorporate some methods into my life. Working with John, and seeing both the level of compassion for his people and the level of professionalism he portrays is refreshing and soothing.
He provides countless amounts of support for what he says, and genuinely cares about what you want and what you are striving for. I am very excited to continue working with him and hope to be for the long haul!”
Matt A. - Online Client
“I cannot speak highly enough of Kempf Fitness Professional and John Kempf's transformative program. John is an exceptional coach with an unparalleled understanding of the human body, yoga, body mechanics, and strength and conditioning.
Participating in his 6 month program was a life-changing experience for me. John's holistic approach to health and wellness encompasses not only physical fitness but also mental health and well-being. His guidance in daily movement, breathwork, yoga, and meditation is truly world-class. I've not only improved my physical health but also cultivated a deeper sense of mindfulness and purpose.
John is the best. Life coaching doesn’t get any better. I recommend Kempf Fitness Professional to anyone seeking to enhance their well-being and make meaningful changes in their lives, families and communities.”
Tori S. - In person client
“John’s dedication to what he does is truly unparalleled. He not only is well educated and informed on the topic of holistic health, but he also lives and breathes it in his own life. He is endlessly supportive and meets his clients where they’re at and tailors his fitness regimen to meet their needs.
From my own experience I can attest that he is always available to answer questions and offer support. John isn’t about the “quick fix,” rather he sets you up with the tools to sustain a healthy lifestyle with a program that really works. I can’t recommend him highly enough!”
John G. - In person client
“John is a master of his craft. Every time I have the privilege of working with him, I continue to chip away at the things holding me back from becoming the person I was designed to be.
I've been working with John since 2019, and I've still never found a program or trainer that gets me results like him. His methods empower my body & mind to respond in the most incredible ways.
John has taught me numerous, invaluable lessons that have improved my life. Self discipline = self love, getting comfortable with the uncomfortable, nervous system regulation, 4-2-4-2 breathwork, working out vs working in, grounding, and the importance of mobility hygiene.
He isn't afraid to meet you where you are at, and just being around his spirit of success raises your own vibration. He has been one of my greatest mentors and models of healthy masculinity. I am so grateful for this man and I can't wait to work with him again. Love you John!”
Dana P. - Online client
“More than results: John is a Light. His experience, education and guidance with movement and food is outstanding. He customized a plan specifically for me as a 50+ year old woman and my specific body type.
What has helped me stick with the program has been his one-on-one guidance throughout: I now embody movement as self-love. My workouts used to be a “to do list” item. Now I move, nourish, and feed my body and soul with a fresh, loving identity.”
Nathan R. - Online client
My time spent with John and the knowledge that he provided is something that I will cherish through time. Through John's training and programs you not only learn a vast understanding of exercise science, correct training procedures and eating to better fuel your mind and body but also simplistic life variations that are easily implementable and effortlessly sustainable.
I am forever grateful for the opportunity to have John be a part of my journey in life. I had the pleasure of learning and growing as an individual from John for 8 weeks and what I took away from it was invaluable. If you are looking for someone to guide you on a path to better health physically, mentally, emotionally or spiritually, then look no further, because you are in the best of hands with John Kempf.”
Kollette G. - In person client
“Just completed John’s 6 week challenge and it was really amazing! John is super knowledgeable and a great teacher. I would highly recommend him.”
Brice L. - Lost 50lb fat in 6 months
“John definitely knows fitness. I have gone on John's workout plans a couple times and lost over 50 pounds combined. I like John’s approach because he takes into account the physical, nutritional, and spiritual aspects of growth and fitness. I keep listening to John and continue to learn in all aspects.”
Linda C.
“John is one of the most passionate and knowledgeable people I have met regarding Mind, Body and Soul treatments. He practices what he preaches and always looks at the person from a full holistic point of view.
Had the great pleasure to meet John in India on the yoga ambassador tour and I would highly recommend him as a true professional who will ensure you get the best approach to healthy Mind & Body. Keep doing your great work and look forward to hearing great things in your mission for the world.”
Brandon K. - Online client
“Hands down you can't go wrong working with John ! As an elite lifter myself I can say his knowledge from strength to health to well being is beyond his years.”
Joselyne J.
“John is knowledgeable and practical in his guidance to improve expertise and health. I was most impressed by how he simplifies movements to make it so easy to follow and apply. He practices what he preaches too. Seeing him eat lunch is the best memory in my head, how salad can look so attractive and enjoyable to eat.
After meeting and working with John, I eat salad everyday and move more since he ingrained in me that it is not hard. It is not, just move, and Eat Real Food (JERF). John, you truly changed my life first by changing my perspective and showing me the easier and fastest way to get the results I want. I am very thankful.”
Brendan S. - Online client
“John provides a wealth of knowledge of the fitness industry, fitness, and diet nutrition. As a coach, athlete, and competitive weightlifter, John has shown and taught me so much. He is an incredibly learned and gifted trainer. You will be guaranteed results from his programming and guidance.”

Teryn B. - In person and online client
“I’ve loved doing this challenge every day and have already incorporated most of the stuff into my regular workouts!”
Drew T. - Online client
“John is an exceptional personal trainer who thinks about the big picture. He will show you how to eat, how to sleep, how to think regarding your own situation, and when you slack he holds you accountable with honesty. He is extremely knowledgeable about anatomy, body chemistry and he brings good brain science info to further detail and explain things that might be giving you a difficult time.
Most importantly, he doesn't train you just to get big, unless that is your goal. He trains you to live a strong healthy life, with no excuses to hold you back. Worth every penny and more.”
Tina K. - Online client
“Great challenge. This was my first with John and I loved it all! He provided so much information, modifications and support that I felt I could only succeed! Thanks for the experience!”
Kele M. - Online client
“John’s program was a face dive into Alice and Wonderland’s rabbit hole. On one end I was a casual lifter with casual results. On the other end I felt like an athlete again. High school me would give myself a fat fist bump. Challenging in all the right ways, just what I needed. Highly recommend it!”
Sarah C.
“John was born to be a leader. You cannot help but be inspired by his passion and enthusiasm. What he is creating is about so much more than just physical fitness, it is about treating the mind, body and soul to deepen your connection with yourself and life.”
Jacob N. - Online client
“By far the best fitness program I’ve ever done. Highly recommend his programs. He creates healthy humans, not just big muscles. Some of the best shape I’ve ever been in. Done a few fitness programs but this has been by far the best one. John is extremely motivating and personable, he’s in it for you, he will call you out when you need it and build you up at your best. Highly recommend it.”
Kayla S.
Ryan S. - Online client
“Hands down one of the best trainers out there. Approaches everything with the client in mind and does a great job of breaking down your fitness goals with very easy to follow training guides and nutrition plans. He does it all honestly.
Very knowledgeable about how your body utilizes the different macro and micro nutrients and what you need to get to your goals. He wrote a best-selling book you can find on Amazon that helps make all your goals attainable.”
Devin S. - Lost 16lb fat in 3 months
“By far the best trainer experience I have ever had! It’s hard to capture everything that he brings to the table in one review, but I’ll try... John has an incredible amount of knowledge in both functional training and nutrition. His understanding of these areas and his ability to easily explain them make it easy to understand what’s required for me to hit my goals.
Outside of the nutritional basics and workout ethics, there is also a portion of his training that focuses on self awareness and general thoughtfulness that really help to round out my workouts...and ultimately my approach to life both inside and outside of the gym.
Working with John is so inspirational. He's helped me to craft a new approach to everything I do. I sometimes like to joke with him and call him my life guru lol.”
Eli D. - Online client
“I’ve met only a few individuals that understand fitness as well as John and can explain things in a way that everyone can understand. If you want to learn something, this guy is one of the best.”
Dayne W. - Lost 10lb fat in 3 months

Ryan M. - Online client
“John Kempf's program was a great way to take steps toward a healthier lifestyle. The content was very easy to follow along with and I enjoyed it so much, I signed up for his 12-Week Program. Thanks John, I'm looking forward to continuing to learn and train with you!”
James P. - Online client
“John has a very positive and uplifting attitude. When you listen to him it’s hard not to get on board. He also practices what he preaches. John is very active posting videos about his own work outs as well as Ted talks and other videos that help you think about what you are doing and why.
I found the group format to be very rewarding for motivation and accountability. For me it’s easy to skip a workout when I’m not in a competition or doing it with others so having a challenge and others to work with was great.
This was fun for me and I’d recommend him as a fitness professional to anyone. It helps to have a group for accountability and the motivation from you and seeing others posts kept me on top of this. I plan to continue using this routine.”

“John is very knowledgeable when it comes to the human body. His discipline is impressive, and nutrition is always on point. But knowledge is only the tip of the iceberg with this one. His love for lifting others up is incredible to witness. He’s creative and very easy to learn from.”
Dustan J. - Online client
“John is a dedicated, well informed patient life and fitness coach. I highly recommend anyone from the beginner to the high end athlete to use John. No reservations.
The combination of meditation, breathing, and mobility (low end yoga) was a very good start toward making healthy habits. When you throw in John’s daily messages from rants and admitting his vulnerable side to practical pearls of wisdom and meaningful tools for focusing our mind in much more positive aspects and paths.
Add to that the TED and Podcast material and we got a tremendous amount of very useful and meaningful personal growth insights and suggestions. Thank you John, you have made an impact in my life in just a few short weeks.”
