I waited a year to write this because I wanted to see if I achieved results while sticking to a "schedule". I have to say that Fit Theory went above and beyond any expectations I had going into it. Not only have I lost 20 lbs but it was enjoyable to do it! Candy makes sure that every one of your workouts is tailored to where you are while keeping it challenging and fun! I have never been bored or felt in a rut in my routine the last year at all. The amenities and flexibility are great and it is SUPER CLEAN. worth every penny of the investment in yourself!

The owner of this place, Candy, was very professional. Candy help me design personalized training routine based on my physical condition and training goal. The training process is highly personalized and adaptive. Candy will adjust the training gradually based on my performance and progress. During a 4 month time period, I can see my body getting into better shape, gaining muscles and being able to handle much larger weights compared with what I started with. I had been working out by myself for many years but working out with Candy was really a game changer. The gym was well maintained, super

I started working out here 3 months ago. Primary reason was that I am coming back from 18 months of no strength training due to Covid combined with a wrist surgery that had been delayed a few times. Wanted to make sure I was fit before getting serious about tennis again
This has been great for me. Candy gives a well balanced workout while also working on areas that need focus due to my layoff. It's working for sure. No issues playing tennis. And...i love the flexible scheduling. Depending on the week I can schedule what works for me rather than fixed time(s)

Fit Theory has high standards for cleanliness and hygiene. It was very spacious and well maintained even before Covid. Candy ensures a good people culture in the gym. She assigns a diverse set of exercises every week so that the routine is interesting/challenging.

Fit Theory is a great choice for anyone looking for a specialized workout plan, and one-on-one training. Candy, the owner, works personally with each client and makes sure you're able to do each workout correctly. As a beginner, it's been very helpful to have her coaching me through each workout. Highly recommend!

Working with Fit Theory and Candy has been a blessing. I don't like working out in big groups, and love the intimate small groups Fit Theory has. I often find myself one on one with Candy, as I am quite flexible with my schedule.
The new gym is amazing, and the location is great. You just can't beat this gym in the area, there is no better personal training and studio around. I'll never leave.

I have had a difficult time finding a good personal trainer. Either it has not been a good fit personality-wise or I could not find a trainer who was available during my needed times. The other problem I was having is my schedule is sometimes unpredictable so I was losing money because of the 24 hour cancelation policy. As an alternative to a personal trainer I started going to a morning boot camp class which was good but a few minor injuries made me realize that an hour is a bit long for a HIIT style workout (for me). Then I found Fit Theory and all my problems were solved. It's a custom 30 minute

Before Fit Theory I was one of those members gyms love. You know the ones that sign up, go a few times and then never step foot in the gym again. After giving Fit Theory a shot, I wound up going 4 – 5 times a week for over a year and a half! Unfortunately my office moved locations so I no longer go there.
The 30 minute workout is customized to your needs and goes by very quickly. Candy is good at mixing things up so the workouts never get repetitive. She is also (sneakily) increasing the difficulty of the workout over time so you’re always pushing yourself. If you think you need a 60 minute

I enthusiastically recommend both Fit Theory and Candy to everyone regardless of age or fitness level.
Fit Theory is a clean, well-stocked studio with a pleasant setting. The scheduling is flexible and the times provided are very convenient to all schedules. The equipment is top quality, the location is convenient and the parking is ample.
Candy is a wonderful trainer. She plans my workout and tells me what to do, which is what I need. She knows my weak spots and helps me work on strengthening them. She counsels and guides me with my overall fitness plan, teaching me stretches to do at home to

I feel fortunate to have met Candy, the business owner and my trainer. She is very friendly and kind to me, and as another reviewer mentioned, with no pretense. She is beautiful inside out and knowledgeable about what she does. I have some injuries and she was able to accommodate that, and the training indeed strengthened me. She is so kind that when I have unexpected difficulties with my reservation, willing to reschedule me. It's also very private and not many people around -- as I am not very fond of lots of people in the same room, I really love it here.
