Absolutely the best training facility. Billy, Jamie and the team at RetroFit are amazing. They work directly with each athlete. At 54 years old, they keep me on the lacrosse field.

Coach Billy and Coach Jamie have created a wonderful community of athletes. They push you, encourage you, and help you live a healthy life. I’ve been coming for almost a decade and couldn’t say enough great things about the gym

No matter your injuries, challenges, abilities, RetroFIT helps everyone find the light they want to shine forward with joy, respect, humor and always encouragement!!!

I have been training at RetroFit since I was in High School and I could not recommend training here enough! I trained here through 3 different stages of my athletic career, High School, College and then Post - College and they have been helping me every step of the way. If you are looking for a place to workout, or have kids who want to take their game to the next level, then Billy and Jamie at RetroFit are the way to go!!

If you are looking for a gym where you feel like family and get personalized guidance not only in workouts, but nutrition and life Retrofit is the place for you. I’ve been going there on and off for over 15 years, and even when you aren’t going Billy (the owner) reaches out and keeps you accountable. There are coaching emails weekly, attention to any injuries, and a truly collaborative environment. Most people who join become lifers bc you make great friends and feel the care and support like family.

I have been working out with Billy for the last 20 years since I was 15 years old! He has made me stronger through high school and college lacrosse, medical school, marriage and having a baby. His knowledge base is endless and his ability to create a workout that fits perfectly with your life is unmatched. I am grateful for all the years I have been able to train with Billy and Jamie at RetroFIT and looking forward to many years to come!

I walked into Retrofit with a bit of apprehension since I had no idea how it worked. What I found was an immediate feeling of acceptance and lots of direction on what to do. Billy Corbett and his team are amazing trainers. When you think you think you have experienced the ultimate training experience, think again, because you actually haven’t experienced it yet.
More importantly, whole families train at retrofit. There is something so awesome about seeing your kids experience the same empowerment and sense of accomplishment that you do. My boys love coming home and talking about their workouts. (I have to admit I do the same).
Retrofit has created a special community and I'm excited we get to be a part of it.

Daughter trained here as a senior in HS to get ready for her lacrosse season, and again over the summer to prepare for college athletics.
The program she was on was far superior than the general summer packet from the college team. Billy also reached out to the team trainer to make sure Retrofit's plan supported the goals the college trainer had.
My daughter has told me she absolutely sees value how Billy and team train, and wants to continue to train with Retrofit in the summers.

We sent my daughter here to get ready for try outs. Chantel and Billy are the best and really got her into shape. She has never felt stronger or more confident. They evaluate well and set up an individual program and work out for everyone that they train. I couldn't be more happier with the results.

Excellent training center and a great value. For the first time in years I feel good and I feel strong. I do the small group classes which mean its one trainer for 1-3 individuals, a fantastic value for the price. I highly recommend them

Billy and his training staff are concerned with safety and form without sacrificing results. I don't know anyone who has had a bad experience with Retrofit and I have been a client for almost a year. I will continue to work with this staff because of their professionalism, motivation and knowledge.
