The Optimum Performance Training. Get started today!

Hello Im Dr. Phil Nicolaou. Welcome to Optimal Fitness and Nutrition. I have been in this industry since 1999 , I’ve worked in health clubs and since 2008 decided to branch out on my own. My issue was the lack of quality of training in the industry. Too many trainers simply count reps and sets and fail to truly give a custom workout! Exercise science has evolved!

With Optimum Performance Training System you will experience posture correction, body alignment, balance enhancement, strength, flexibility!

After my own battle with overcoming Lyme disease, exercise and a healthy lifestyle saved my life. It goes beyond losing inches, losing body fat or a physique transformation, that is just the start!
I take a unique approach to health and wellness. I look at and coach on Stress management, Lifestyle and weight management, optimal sleep and nutrition!
I am the only trainer in the city of Philadelphia with 4 Master Trainer certifications from 4 of the most prestigious fitness schools in the nation and a Doctorate in Exercise Science and Post Rehab since 1999!

Dr. Phil rather I call him Phil, but for sure he earned his title with me. He always kept in touch with me by text, making sure I was doing ok… Only trained as needed, was my moral support as I began to lose faith in if I was ever going to be without pain and weakness. Today I have occasional normal soreness after a long day splitting firewood or hard work out at the gym, for sure Dr. Phil made it possible for me to leave the pain behind. Dr. Phil takes ownership in his patients, he understands the body and helps educate you how to understand your own body. I can’t believe how what I thought was hopeless is now my getting use to being without pain… My hats off to Dr. Phil, thank you for giving me back my confidence and making it possible to rehabilitate my shoulders and take away my years of being in pain and weakness.

Philadelphia Personal Trainer Phil Nicolaou knows that muscle imbalances prevent the body from functioning properly through every day life. So if they are not corrected, they will hinder your results! The core of my system allows me to determine how well your body moves so that I can maximize your body’s muscular alignment which in turn gets YOU Optimal results!

My wife and I started this journey about 4 months ago. We weren’t sure what to expect and were a bit apprehensive about hiring a personal trainer. I have to say that Phil has exceeded our expectations. He comes to the sessions prepared, follows up with us during the week and changes the workout as needed. We started to see results in about 2 weeks and definitely feel that our core strength has improved. Do yourself a favor – just start, you won’t be sorry

Phil was an excellent trainer- I enjoyed our workouts together. He answered all of my nutritional questions and was accessible. I could tell that he cared about my well-being. I would recommend him to anyone who’s looking to get fit!

Trainer Phil, Dr. Phil, did a full assessment of my shoulders conditions. He gave me specific exercises and things to be mindful to assure I didn’t make my injuries worse… From October to December, we rebuilt my rotator cuffs, which I did not know are the building blocks for shoulder stability. Before I met Dr. Phil, I had made an appointment at Rothman Institute, there I learned the approach I worked out with Dr. Phil was confirmed as the best for me. My injuries were caused by over use, and not from an actual accident, but even at age 52 I was not about to give in to physical therapy only I didn’t want to lose all my other muscles. Shoulders kept me from doing everything, the pinching would not even allow me to lift a coffee pot without pain, working out at the gym was very limited. By December, Dr. Phil had me at about 70%, he even said I could be bench pressing again by Christmas… For sure, he got me benching again, and even taught me the right was to bench. Through Jan & Feb 2017, as the rotator cuffs were no longer injuries but building strength, Dr. Phil pushed me little harder. Now March and I am benching heavy once again, all my other lifting has also increased.
