About me

Hey! I’m Constantino Diaz. I’m from Spain, but I grew up in Athens, Greece, and these days I split my time between Massachusetts and Spain. Since I can remember, I’ve been all about sports—especially basketball and tennis. When I was 18, I had a pretty serious knee injury, and that’s when I really got into fitness and started learning more about how the body works.

That passion led me to study Sports Science in Madrid, and I also became a certified basketball coach through the Madrid Basketball Federation. Since sports and nutrition go hand-in-hand, I decided to take it further and got certified in nutrition from the University of Athens.

After moving to the U.S., I started working as a personal trainer. Now, I’m kicking off this online adventure to stay connected with my clients and keep doing what I love—no matter where I am in the world. Let’s keep moving, training, and pushing forward—together!
