Testimonials

I have nothing but the best to say about AJ as a coach.He turned me from an amateur to an IFBB professional bodybuilder within a year. What I admire most about AJ is not only his knowledge as a coach but also the confidence he instills in his athletes. He reminds us that this game is just as mental as it is physical.He's extremely dedicated and meticulous to his athletes and cares about our health and success just as much as we do. I feel honored to have AJ coach me and would recommend his coaching to any athlete looking to work for it and take their physique to the next level. AJ, thank you for all you've done for me as a bodybuilder. I'm eternally grateful for you. 

Coming from the Netherlands there weren't many choices if you really want someone knowledgeable. In the years I have worked with great minds like Matt Porter (RIP), John Meadows (RIP) and Phil Viz. All these coaches have helped me build my physique and learn new things, they all have great attributes to each of there own. After a few years of working with AJ it's safe to say he is so versatile and knowledgeable, he really exceeded my expectations. Fast reply's, exact details and even when peaking for my shows he sets up his alarm to wake up, so every box is checked and I know what to do. He does not leave me second guessing anything and this gives a lot of trust going into a show or deep into my offseason, I just have to make sure I execute. This is the exact same thing I try to do for my clients but he sets the example. Definitely a great man leading and paving the way.

Reaching out to AJ about five years ago when I wanted to step up my competitive level in the bodybuilding world was one of the best decisions I’ve made not just because of his work in the bodybuilding world, but because of him as a whole. Overall, he cares about your health, as well as your passion as a bodybuilder. We all want to win we all want to be the best. He understands that as a coach myself, he knows exactly the level I want to be at and the level I know I can be at he puts into me as much as I put into the program. I am extremely grateful for him as a coach and a friend in my bodybuilding career. I know I would never have anybody else by my side through this process. He’s a great family man, a man of God, a man of faith and understands the past has sub blemishes, but he’s always positive moving forward. This is why I connect so well with him I would highly recommend him to anybody wanting to step up their game mentally physically and emotionally. He has helped me along this journey to find my absolute best and to me we haven’t even started. God bless my brother.!

thank you for the 6 months we worked together back in 2022. Learned an insane amount of information and apply it to this day as a “lifestyle”. Learned a lot about digestion/ high intensity methods first thing in the morning/ to “super saturation” days, and proper training. I spend more than half the year traveling the world in the past year and am able to stay this lean is pretty mind blowing ! Thank you Aj 

I hired Aj originally back in 2020 for a growth phase after a bodybuilding contest I did. Although I only worked with him for a short period of time, the results I got were insane. Not to mention, I saw how passionate and caring of a coach he was.

Fast forward to 2024, I retired from competing and decided to do a local show to see how I could do. I quickly got in touch with Aj again after and have been working with him for about 4 months, working towards a lifelong goal of mine and getting my pro card July 2025.

I’ve worked with several coaches and Aj by far is the most knowledgeable as well as the most caring, genuine dudes I’ve ever had the pleasure to work with.

It’s not just bodybuilding, it’s about keeping me healthy while Pursuing the goal. Aj covers all aspects from bloodwork to gut health, to blood glucose levels. He’s all about optimizing health and performance which I truly appreciate.

Aj is always prompt in responding to questions I have as well as never makes me feel stupid for asking questions. He makes me feel like I’m his only client which I’m sure is difficult considering the plethora of clients he has worldwide.

It’s been an honor to be able to get coached by someone like Aj and represent him.

From August to December we’ve put on about 30 lbs of mass, and have maintained body fat low.

This is by far the best I’ve ever looked and felt.

I highly recommend Aj as a coach, a mentor and overall a great person to have in your life. As weird as it sounds, knowing that I’m working with the best, pushes me to want to be the best, and try my best in every aspect of life.

I started working with AJ as someone that wanted to just get in shape and get a diet plan.
What I got was far more than that AJ took me on as a lifestyle client providing me with his expertise and years of nutrition knowledge.
Not only did I get a plan custom to my needs but also taught the importance of supplements needed along with nutrition.
After body recomp and getting into the best shape I have have ever achieved. He gave me the confidence to want to compete and further me physique goals.

As a competitor he’s on it everyday most time daily checkins switching the plan as he sees needed I never have to worry about showing up out of shape or questioning anything. He brings the #FATFREE condition every time.
Rather it be lifestyle or competition he is always there to answer any questions I have and provide me with the best path to follow.
Never left me to wait. If anybody’s looking for a great coach and mentor above all I would not hesitate to look any further. Best decision I could have made never have regretted it.

I had the honor and privilege to be coached by A.J for a full calendar, I started my bodybuilding journey in 2013 I went through 4 different coaches within that time frame and none of them paid attention to the details like A.J did! From the timing of water intake to gut health, vitamin intake with certain meals DETAILED TO A T! Working with him made me beyond accountable for each day, to win the morning and win the day! Come peek week it was day to day,hour to hour check ins. We did a 8.5 week prep due to me catching Covid before the prep began. Even post show he kept me tight and weight up! AJ is a workhorse, and expects the same from all his clients prep or lifestyle! There is no other coach I would recommend or work with ever again!

In February of 2021 I was introduced to Aj through a mutual buddy. I had become stagnant in my growth and needed a change. I’d never really used a nutritionist before and always just tried things on my own. It helped me to maintain, but there was always a plateau that I could never get past. Over the past two years working with him and trusting him with my nutrition has completely changed my metabolism. My growth has been unbelievable but not only that my self-esteem also!
His knowledge, his passion and his drive are second to non. I’m so thankful to be able to call Aj my coach, friend and brother in Christ. Thank you brother for all you do!

My journey with Aj started just over 20 months ago. We literally started from scratch after a major injury I suffered in Feb 2021.

Aj is a master mind behind what he does, his not only a coach but his a mentor and brother that has been there for me at my lows to all highs. He really thrives on your well being and everything is done with the intent of your health being first.
Without his guidance I wouldn't be here today in the best condition of my life.
Can't wait to keep working together and seeing what we can achieve in the future.

Thank you

“AJ is a different level of coach. As someone who has worked with most top coaches in the industry, AJ sets the standard. He’s the only coach I would work with as he challenges me and keeps me learning which isn’t easy to do with my credentials or background. Most importantly we do it all with clean blood work and putting health first as this is a lifestyle and constant pursuit in this sport.”

“There are coaches and then there is what AJ does. AJ challenges you as a person, as a man and through all areas of your life to become the best version of yourself. He mirrors and lives what every man should strive to be like.”

When my doctor suggested a colonoscopy, I didn’t hesitate. The results came back perfect, so the next step was trying Linzess. I thought, ‘If it’ll help, sure.’ But after months of taking it, and spending thousands of dollars, I was still dealing with the same issues. That’s when I found AJ. In just three months, through targeted diet changes and supplementation, AJ accomplished what doctors and prescriptions couldn’t. Yes, AJ will help you get in shape and feel confident in your body. But his real superpower is what he does for your health on the inside. His knowledge of nutrition and supplementation is unmatched, but what truly sets AJ apart is his character and meticulous attention to detail. I’ve seen AJ behind the scenes, and I can honestly say this: he gives the same energy, focus, and care to someone with zero followers as he does to a millionaire. AJ genuinely cares, and that makes all the difference.

I’ve been working with AJ for almost a year now. When we started, I practically pushed him into doing a rush prep just eight weeks out from a competition I had in mind. AJ told me it was possible to do it, but we weren’t sure if we would go through with it. He said I had to give it my all and see how my body responded in such a short time. This was a challenge for both of us, as AJ didn’t know my body yet. Even so, his work ethic, dedication, commitment, and attention to detail made it possible for us to achieve incredible changes and an amazing result in just eight weeks—an extremely short time for an athlete and coach who are just starting to work together. We won the competition and qualified for the Mr. Olympia. The second part of our journey together was the challenge of gaining muscle while in prep. We needed to add some size between the competition we won and the Olympia. We managed to compete 4 pounds heavier, with the weight distributed much better and more balanced. I had significantly more muscle detail and better conditioning at the Mr. Olympia, all achieved in just about 16 weeks. I consider AJ to be a disruptive coach who pays great attention to detail, and I believe that’s what makes him stand out. He experiments a lot, but from what I’ve seen in his stories and our conversations, he tests these experiments on himself first before applying them to us. You can see that he’s someone who leads by example in every sense, and that inspires us as his clients and athletes. His dedication motivates us and makes us want to work hard because the person giving us directions is following them himself. He is an extraordinary combination of old-school methods, theory, practice, and new learnings and innovations.

So I had been following AJ on social media and seeing the wildest result with his clients since about 2016 and had met him briefly at NYPRO. The great vibes and amazing energy i got from just a quick little chat was great and I said 1 day I'm going to hire him and see what we can do. Fast forward to early 2021 i had reached out and we had a phone call to see if we were a good match and thankfully we were. Before we dug deep into gym and prep talk we spoke about life and what my past was like and family life. We had clicked on so many levels that we formed a brotherly bond and not only was he going to get me in the best contest shape of my life, he was also helping me be a better man and father and husband. His kind words and approach on how to handle situations was helping me more than he would ever know. So now onto gym and contest prep. Holy shit did he get me into the best condition and shredded while being full and looking freaky. His approach and methods made dieting easy and not miserable and not stressful at all. He does this super saturation days and I was eating about 1200g of carbs in one day and waking up I was just about the same weight I was the day before but looking freaky. I had never felt so great and healthy while in contest prep in the past but this time I felt amazing. AJ has helped me in so many ways and he still does with his posts and stories and for that I am forever thankful for him. He is a great man.

I had the privilege of working with Aj Sims in 2020 in Preparation for a Body Building competition. My experience through this process was excellent and only requirements on my end was to follow the plan Aj meticulously laid out for me and give 100% physically and mentally. When you work with Aj in this capacity you quickly understand the knowledge and experience he has not only for the physical but also the mental aspect. I feel he is able to connect with the client not only because of the vast experience he has had but also from going through this himself as and athlete and now as he lives this lifestyle day in and day out. He not only can talk the talk but walks the walk. What is in my opinion more important than the diet and workout plan he provides to his client’s is his knowledge and attention to health. If you have the opportunity to work with Aj you will feel the desire to use the experience to become better in the other aspects of your life because of the way he connects with you as a person. He is one of the best nutrition and athletic coaches out there but since I’ve known Aj for over 10 years what I personally find the most valuable you can learn from him is the is discipline it takes to sucessfully complete a prep and Insert that to your everyday life to make your life better long after a competition is done. He is an example of how to improve yourself daily, physically, mentally and financially if you apply what he has to give. His dedication to his clients is extraordinary. What Aj has to offer is on another level than anyone I know of. He is a complete Coach and Mentor.

I started working with AJ in 2023, and he has been instrumental in helping me achieve my absolute best. He is fully hands-on throughout the entire prep process, providing unwavering support and guidance. I’ve learned so much from him, using completely new approaches that have transformed the way I train.

I never imagined my body could look like this, and I am incredibly grateful to have him as my coach. If you’re looking to get in shape or start a prep journey, look no further—AJ is the one who can help you reach your ultimate potential.

I have been coached by AJ for four years, and in that time, we’ve improved with every single show. I’ve gained an incredible 40 pounds of stage weight, earned my IFBB Pro Card with AJ by my side, and even made my pro debut.

AJ’s commitment to the smallest details, his clear and detailed communication, and his meticulous care are absolute game-changers. He has not only helped me become a better competitor but also a better coach, father, and family man.

One of AJ’s greatest strengths is that he gives the same level of attention and care to beginners as he does to Olympia-level athletes. He truly wants you to succeed in every facet of your life and works with you to optimize every day for success.

Working with AJ has been one of the best decisions I’ve ever made—it’s been a journey of consistent growth, both on and off the stage.

My name is Charles Ikle, I am 27 years old and I have worked with AJ for 2.5, going on 3 years. He was essentially my first real coach in Bodybuilding as he got me after my first show where I really did not know what I was doing nor trusted how I was being guided. I hired him at 4 weeks out to take over after that show into my first ever rebound phase. AJ has taken me from a middle of the pack heavyweight to a Nationally competitive superheavyweight in 2 years with over 40-50lbs stage weight gained in better condition MORE notably while keeping and helping me become healthier while doing so. AJ is health conscious first, explaining every little detail to a T while teaching me how to do things properly and understand WHY I am doing it. Bodybuilding aside, he is an amazing mentor & father figure that's helped me through trialing times mentally and brought me closer to name my faith in God/Jesus Christ. He knows my body perfectly and takes any stress away as all I have to do is execute and work. Churning is a lifestyle that I am proud to represent and am truly grateful for his piece in my journey to the big stages.

I consider him family at this point and will never hire another coach for as long as I am competing at this level. From lifestyle, to the stage, and every detail in between-- this man gives you the tools to become the best & most optimal version of yourself in EVERY way. His knowledge level on training, nutrition, gut health, hormones/PEDs and overall health markers is second to none and he stays out of the crowded dramatic fitness scene bringing light to a very dark industry.

As a client he has gotten from the beginning and built from the ground up, I am a prime example of representing all of these principles and would not have gotten here without his guidance. Hiring AJ was one of the best choices I ever made and your expectations will be crushed if you too decide to do so yourself. Let's CHURN!!!!!
