About

About

My love for health and fitness started when I was young. Today, I’ve been fortunate to turn my passion into a thriving profession. Since 2016 I’ve been working as a certified personal trainer and nutritionist in the Princeton and Hamilton NJ area, guiding my clients towards a healthier lifestyle. Through working with a diverse group of clients, I’ve come to realize that everybody is unique, each with their own goals and lifestyle. Using my bachelors and masters degree education, along with my years of experience, I have constructed in-depth online training programs that are suited for everyone's needs ranging from body transformations, strength training, HIIT, weight loss, functional training, tennis training, soccer training, senior citizen training, and healthy lifestyle optimization. For those looking for an in home personal trainer, online personal trainer, personal training studio, elite personal training, or small group personal training, we've got you covered.

WHAT PEOPLE SAY

Avesh J.

I met Demetri a few years ago and he helped me get in the best shape of my life. I lost a good amount of weight, gained a lot of strength, and felt better than I had in years. He has an excellent knowledge of strength training, fitness, and nutrition. His personalized workouts are challenging but fun, taking into account any injuries, and he does a great job of helping you gradually progress to more difficult exercises. Not to mention helping me so much with online personal training during covid. I would not hesitate to recommend him!

Demetri is an excellent personal trainer. He is very knowledgeable about kinesiology and exercise physiology, so he prepares training sessions that are individualized. He adjusts training sessions based on how my body is doing, and he has a keen eye for correct form so I know that I won’t get injured. Demetri challenges me just enough to keep me motivated and progressing with my goals. Thanks to him, I am stronger, doing workouts that I never thought I would be doing, and am enjoying them. As a dancer, I am grateful that the training sessions with him allow me to still dance full out. I think everybody should have a personal trainer as qualified as Demetri.

Miriam E.

Demetri's educational background combined with his obvious passion for fitness make him an excellent physical trainer and health coach. He will listen to your goals and personalize a program designed to meet your individual needs, ensure you use proper form and will adapt the program as you progress. He will make sure you perform exercises correctly for maximum achievement without injury and will share his deep understanding of exercise and nutrition. His in home personal training helped me so much and I cannot thank him enough!
