About Diego

I was born in Madrid, Spain, and soccer has always been my passion. After earning my degree, I became a professional model, working in Europe and Asia for seven years. During my modeling career, I recognized the importance of health and fitness for both aesthetics and well-being.

In 2013, I moved to Barcelona, where I earned a Master's Degree in Nutrition while working as a personal trainer. Later, I relocated to Paris, where I specialized in training models, athletes, and business clients.

In 2014, I ventured to Los Angeles to pursue a career as a Health Coach, working with a diverse clientele from business, entertainment, and athletics. You might know me for my invention, the Nucleus Core Pro, and the Nucleus Core Method, which I developed. With 13 years of experience in Barcelona, Paris, and Los Angeles, I specialize in body transformations, strength training, post-pregnancy recovery, and functional training.

I'm dedicated to helping people transform their lives. Visit my website to read testimonials, Men's Health articles, check out my book, or watch fitness TV segments featuring my work.

Rarely do you find a trainer that is as committed to his craft as Diego is. I've gone through quite a few trainers and the difference between Diego and other trainers is that Diego actually cares about his clients. He is genuinely happy to see his clients achieving their goals. I would definitely recommend him to anyone of any fitness level. He is knowledgeable, professional & dependable. He's helped me with personalizing a workout and a diet customized to my body. He’s helped me gain 5 pounds of muscle and I’ve dropped 5% in body fat! If you're looking for a personal trainer, Diego is the guy!
