After 6 months, of training under him, my flexibility and endurance have tremendously improved. I hit new personal records almost on a weekly basis now. Diego is very thorough with his workouts and very understanding of my strengths and weaknesses. I have lost close to 25 pounds and almost tripled my max since starting. I can’t wait to see what the next 6 months will bring!”

“My first training session I was sore from muscles I didn't know I had. In each training I get to further understand how my body works and how to engage my muscles. Diego's knowledge is worth every penny and the results are very noticeable. One weekend i was cutting a watermelon and my sister complimented my newly acquired back muscles ... now she and my friend are also training at Havoc.”

“Before signing up, I have lived an active lifestyle competing in martial arts competitions and working out relatively consistently. However, I wasn’t where I wanted to be. I asked Diego, the owner of Havoc Athletics, if he could help me with some issues that have plagued me for the majority of my athletic life; chronic neck and hip pain, lack of strength, and nutrition plan that did not consist of me starving myself to look the way I wanted. I remember the first time entering the gym and realizing just how much work there was to do. My lifts were at a novice level, and despite the martial arts training my strength levels were extremely weak. Since then, I have worked closely with Diego to improve my strength, mobility, and most of all my quality of life. The great thing about Havoc Athletics is that they understand that to love a healthy life you have to live and his methodical approach to fitness allows you to get fit, be healthy, and enjoy life. The best investment I’ve ever made is my health. “

“With upcoming fights on the horizon, I knew I needed a program that could truly elevate my performance. Since starting the program, I’ve seen significant improvements in my strength and speed. Focusing on movements like sprints and jumps has notably increased my power and agility, directly boosting my overall performance in the ring. What I enjoy most about working with the team is the hard work and dedication that everyone puts in. Diego, my coach, is incredibly disciplined and committed to helping me reach my fitness goals. His consistency in pushing me and my peers to strive for our best is truly motivating. The competitive team environment during training is invigorating, and I appreciate that Diego, as a fellow fighter, understands the specific exercises and workloads necessary to enhance my performance. I would highly recommend Havoc to anyone looking to improve their athletic performance. The results I’ve achieved in strength and conditioning have been remarkable, thanks to Diego’s efforts and dedication as a coach. If you’re serious about elevating your game, this is the place to be!”

“His programming is top notch and has rare ability to pivot when needed to get the most out of your session. Couldn’t recommend highly enough.”

Jamie M.

“Completely took my fitness and athleticism to the next level while also eliminating a lot of the nagging pain I’ve accumulated with years of lifting".”

“I’ve trained Muay Thai for many years and figured that was all the exercise I needed to stay in shape.  So, when Diego said he’d like to train me I was intrigued but a little skeptical.  I’m sure glad I accepted his offer.  Diego is a great coach and trainer who knows how to push me hard enough to achieve new limits without pushing me to the breaking point.  He listens to my concerns and modifies routines if something is hurting.  Diego’s program is a great blend of weight training, plyometrics, and mobility.  At the end of each session, I KNOW I’ve worked out.  After my first 8 months the physical differences are evident.  While I’m still lean, my physique is bigger and more defined.  My posture has improved - particularly in my shoulders.  My core and back are strong.  Thank you, Diego, for starting me on this journey and guiding me through it.  Looking forward to more!”

Garry K.

“After struggling for over a decade with chronic illness, debilitating joint pain and swelling, I began my fitness journey with Diego’s guidance. At the time, I knew nothing about lifting weights, was overweight and couldn’t jump, squat or run. “

“With Diego’s help, I’m now able to squat more than my bodyweight, jump hurdles I never thought possible, and I’ve lost 20 lbs. Along the way, I’ve learned that while motivation is great, its discipline and consistency that truly produces results. I’ve also learned how to fuel my body with nutritious meals that support building and maintaining muscle.”

“Beyond the physical changes, my confidence in my abilities and appearance has grown tremendously and positively impacted other areas of my life. I am so grateful for Diego and Havoc Athletics. Choosing to train with Diego and has been the greatest investment I’ve ever made in myself, and I can’t recommend him enough!”

Samantha

“ I always felt awkward lifting and had no idea what I was doing. Since working with Diego, my knowledge and abilities have expanded tremendously. The program he had set for me took my endurance, strength, agility, mobility, to a whole new level. And the proof is in my last two fights. Not only does he teach me how to “get strong” but explains the science behind what we are working and its purpose, he is also always willing to answer any questions I have through the workout. He tailors the workout specifically for me in my goals and is flexible to make adjustments if I need them. Highly recommend Havoc Athletics if you’re serious about learning, growing, getting fit, and reaching goals beyond your wildest dreams!”

-Astacia, Ambush Muay

From the moment we started working together, his expertise made all the difference. From day one he has supported my ‘crazy’ goals and his knowledge of fitness and nutrition has not only helped me build strength and endurance but also boosted my confidence. My entire mindset has shifted. 

Heading into our sessions, I always feel a mix of excitement and nervousness, and that's because he pushes me outside of my comfort zone. While I might feel a little afraid of the challenges he sets, I also know that these challenges are exactly what help me grow. As a result I leave each session feeling proud of what I've achieved. I truly appreciate how he helps me reach new limits and grow in ways I never thought possible!

Whether you're just starting out or an elite athlete, I highly recommend Diego—he's an incredible trainer who genuinely cares about his clients' goals and progress.
