Peter Babi

Personal Trainer

A student of Physical Therapy Assistant, and certified Personal Trainer from WITS. I come to the field with a fresh and broad spectrum of ideas.

Incorporating the body mechanisms in ROM, joint flexibility, the client’s desires and abilities, I help design programs tailored to fit each individual’s needs. Knowing that the body is a group of systems and working to synchronize these systems is key. Listen to your body, and with my help we can guide it to great heights.

A work out should be fun, something you look forward to doing. Yes, there will be some soreness and aches but not pain. So join me on this fun yet very gratifying journey to a better life!!

Revathy “Rev” Rajah

Personal Trainer

Throughout the ups and downs of adult life (including three c-sections and three beautiful daughters!), I always tried to stay active and reaped the benefits.  Now, I am fitter and stronger in my 50s than I was in my 40s. As an older woman who fell in love with strength training, I want to turn the stigma of the older, weaker person on its heel. By paying attention to a few fundamentals like strength training with progressive overload, mobility, nutrition, and cardio training, we can become stronger as we age. Aging is exciting!!!

"My approach to Fitness Training is based on balance, consistency & knowledge. My goal is to coach you and educate you so that you need me less and less over time for telling you 'what to do', and more as a guide leading you to what more you can do. No matter what your situation, with the right guidance and support, you can achieve your goals no matter what they may be."

Ezzy Reyes

Personal Trainer

I served in the United States Marine Corps for 5 years, and am earning my Bachelors in Exercise and Health Science. I decided to become a Personal Trainer because fitness has always been a passion of mine. I want to be there for those who want to bring in change.  There’s nothing more important to me than helping somebody go through an experience that challenges them and makes them happy and more confident.  I want to share the benefits of training and growth mindset that contribute to a healthy lifestyle, and also allowed me to fully recover from a serious auto accident.  I will be here to guide you every step of the way of your journey

David Pepin

Personal Trainer

When I started training in the 70’s I had very little guidance. Through the years I have met many people who educated me and helped me understand the science behind training. I want to be a resource if people have questions.
I am very passionate about posture, movement, and strength training. I want people to get the most out of their training.
