I had the opportunity to meet Charlie a few days ago for the Strong First Barbell Workshop and I must admit the experience was amazing.

We felt safe and happy with Charlie and his team, and also they kept the day interesting with every step they explained to us.

I´m looking forward to be there again and learn more about strength.

I attended the StrongFirst Kettlebell 301 with Team Leader Charly in Mexico City. The chosen facilities were well equiped, appropiate, spacious and clean. The support coaches were attentive the whole session. Charlie himself conducted all the workshop in a respectul manner, showing his deep knowledge and plenty of experience in Kettlebell training. He was willing to answer all questions. All the session was well organized. Congrats.

My experience working with Charlie as a remote coach has been outstanding. Charlie has consistently demonstrated a deep commitment to helping me achieve my strength training goals. Despite the distance, he has ensured that we maintain constant communication and that I receive an adequate follow-up and support.

The "Built Strong" training program that Charlie recommended has been a fantastic experience. This program focuses on strength and hypertrophy training using kettlebells and body weight exercises, making it both enjoyable and challenging. Charlie has always been available to answer my questions and provide feedback on my technique and progress, which has been crucial to my success.

Thanks to Charlie, I have made significant gains in my strength training and muscle growth. In just four weeks, I was able to perform a shoulder press with a weight of 32kg, which was previously a struggle for me with just 28kg, not to mention that I look now way more muscular. This is a huge accomplishment for me and demonstrates the positive impact that Charlie has had on my training.

In addition to being an exceptional strength professional, Charlie is also an excellent human being. His genuine passion for helping others achieve their goals is inspiring, and his dedication to his work is truly admirable. Charlie has always been there to help and motivate, even when things get tough.

In conclusion, I am incredibly grateful for Charlie's support and guidance. He is without a doubt the best coach I have ever had the opportunity to work with and I would highly recommend him to anyone seeking to improve their training and achieve their strength and fitness goals, definitely I'll keep training with him. His combination of dedication, experience, and knowledge make him an exceptional coach.

My first StrongFirst Mexico workshop, and the experience of having been taught by Charlie, is more than excellent, with a wide domain of the subject, with the ability to impart things through "blocks" and at the end to unite the whole subject, in addition to the demonstrations and corrections in a very clear way, left me a very good experience and I learned a lot, and with the desire to continue learning the StrongFirst Mexico methodology.

What can I say about Charlie? All of the reviews below are correct. Charlie is a fantastic instructor. He first does a thorough evaluation of your movement patterns, and then he programs a routine specifically based on your strengths and limitations.

I was hesitant to get started on a program as I had recently had a pretty serious cardiac diagnosis, but after talking with my doctor and Charlie we were able to come up with a plan that would get me stronger and more fit. Charlie has been very supportive and the results have been better than I could've hoped for. All this in less than a month!

I don't know what else I can say except that I recommend Charlie without any hesitations!
PS If you have issues with mobility ask Charlie to set up a session with Sam (also a fantastic KettleBell instructor) and she will get you fixed!

Charly is a great Coach and has a lot of knowledge, he enjoys to share his knowledge to make people become better person. He is always open to guide you and help you. He is willing to guide people to be stronger than ever. I loved to be part of all workshops driven by Charly. Thanks a lot coach!

Strongfirst Team Leader Carlos Guendulain is an excellent personal trainer. Not only does he have the experience and the background required to train others, he is always concerned about his clients needs, health and safety.
Charlie has given many great workshops through StrongFirst. However, my favourite one has been the Bodyweight workshop by far. I highly recommend his work! Charlie is a great trainer, human being and friend!

Charly is a great and professional instructor. His experience and the way he share his knowledge is one of his main strength. I am really happy to be part of this workshop and met Charly!! Awesome Coach!

Charly has changed me a lot in a short time, he is a great coach and a great person, he really loves it in his work, you can see the passion he has for him. He would like to be the same as him or even better because he is too good: 3

Charly me ha cambiado muchísimo en ya poco tiempo, es un gran entrenador y una gran persona en verdad se la rifa en su trabajo, se ve la pasión que tiene hacia el. Quisiera ser igual que el o hasta mejor por qué es demasiado bueno :3

I attended this Foundations course and I really liked it! I learned several very interesting technical things and I went back to see some concepts that are fundamental. Thanks to Charlie for the professionalism and dedication to the course, I left very satisfied and eager to apply everything I learned immediately. A highly recommended course!

Carlos is an excellent instructor, he is very clear when he explains the moves. It is very clear that he practices what he preaches. It is an honor and a privilege to train with him.

Carlos was the one who taught me the Hardstyle Kettlebell and his teaching, patience and passion with which he teaches was so good that I ended up in love with the method and today I am also a certified instructor. Charly is still my instructor and every day I learn more, now not only for my training, but also to be a better instructor.

I've been training with him for a few months. His way of teaching and taking you to achieve your goals is second to none. I am very grateful that in a few months I completely changed my perspective towards exercise, of leading a healthy life and of including training in my daily routine. His patience and dedication to us, his students, is admirable. Güendulain lives and transmits his philosophy in everything he does.

Fausto Ramos
Carlos is an excellent coach, he manages his sessions very well, checks that people are doing the practice with good form and uses all the tools learned from the strongfirst methodology to obtain the best results.

What can I say about Charlie!!!! I’m soooo thankful with him. I’ve been working out for half a year, and I’ve seen the changes. I’m more fit, stronger, achieving every goal I’d set from the begging and beyond, and getting into others that I didn’t imagine I could even think about them. Incredible the way he encourage you to keep on going, further and also teaching the discipline that you have to get in order to get the results you want, with that gentle and human touch.
Never the less that he is a remarkable human being with that special touch he has and patience to explain the do’s and the doesn’t, with a perfect technique; I can get to improve with every single day of trainning.
In my personal experience, I can’t go regularly to the same gym, ‘cuz of my work (lifestyle), so he had to prepare and teach me the correct way to performed the exercises, and practice everyday, I can tell you that even people at my work and the gyms I visit all over the country they’ve seen my remarkable change.

So I just want to say Thank you for your effort, patience and the professionalism you project in every single session you give.

Dave Zamora
Carlos is both an exceptional coach and a human being, working with him has been one of the greatest experiences of my sporting life. Coming from a career in long distance training, Charlie helped me reshape my entire body composition into a lean, mean strength machine. I hope to keep working with him for the time to come as I’m sure he is one of the greatest coaches of the kettlebell sport.

Erick Chávez
An excellent coach and person, constantly looking for new challenges, new routines, better results and above all is very devoted to his work.

Great coach, in addition to taking care of each position in each training and helping you achieve your goal, it fills you with knowledge about what you are developing in training, which broadens your vision and takes you into this wonderful world of functional training.

It is as important to develop body strength as mental, it makes you be constant and disciplined.

No doubt injected passion for this sport!
I have a couple of months training with him and I just can not wait for another day of training!

I have noticed more strength and coordination in my training, a lot of energy and incredible results in my body composition.

I just have to say thank you Coach!
You're the best!

Carlos has been my personal trainer for almost four years, and in that time he has helped me to be stronger every day, healthier and sexier. He is always aware of the technique of execution of the exercises and transmits the passion for kettlebell training. Without a doubt he is the best StrongFirst instructor in Mexico!

He was my coach for a little more than a year and I highly recommend him, he has great attitude, shows a lot of professionalism and love for his job, personally he helped me a lot, he's always aware of the techniques to improve our execution, he passed on to me the love for kettlebells and now I look forward the course of these in StrongFirst Mexico.

Carlos, Charly as I first knew him, motivated me to train with excelent attention -and patience, since I was completely new at training-, he explains every exercise with detail so one can make it apropiately. As I kept training, he made me understand limits are only in our minds, and impossible is nothing.

He’s so great in his job, he help me to get to my goal, such a great trainer, he’s good explaining all the exercises and if you are doing something wrong he teaches you to learn in your mistakes.
A really good instructor

Carlos has inspired and motivated me to get involved in Strongfirst training. He is an excellent personal trainer. During each session, his full attention is on his trainee, correcting and making sure each excercise is well executed to avoid any injury.
