This gym does have a steeper price although it absolutely makes up for in not just equipment but also community. I’ve personally have had people help me with proper form and have friendly work ins. Also it’s hardly overwhelmingly busy. I hope you choose fit gym because it is a great place.

I’ve been a member of several different gyms over the years, and can state unequivocally that the FitGym experience is simply the best available. The gym feels very different in that it is Always clean and the owner, and every qualified personal trainer are all very knowledgeable, friendly, professional, and supportive. I would give them a sixth star on my review if I could.

Fit Gym is the best gym I’ve ever been to! The facility is always spotless, which makes every workout so much more enjoyable. The staff and owners are incredibly friendly and welcoming, creating a community vibe that keeps me coming back. The owners go above and beyond, always checking in to make sure members feel supported and motivated. The equipment is top-notch and well-maintained, with a great variety for all types of workouts, from strength training to cardio. Fit Gym makes you feel right at home. Highly recommend.

This gym might be small, but don't sleep on it! The friendly atmosphere alone will keep you coming back.

Always clean, which is hard to do for a 24 hr gym!

It's so well-equipped you can perform virtually any exercise. Moreover, equipment is top-notch and meticulously well-maintained. You only need to mention an issue and Mike and staff are on it!

It's got group classes, personal trainers, and a brand new addition of a physical therapist. Bonus: there's often a well-behaved dog, or two, around to pet.

Get after it at Fit Gym!

I love Fit Gym! I’ve been going here for over 8 years and each improvement Mike adds to the gym has been great. They continually add new equipment and classes that make the gym experience enjoyable. Truly a judgement free zone where you are able to work out exactly as you wish. Mike is very accommodating if you have any questions or concerns as well. Definitely recommend!

Literally the BEST gym in Jefferson County and certainly beats all the Corporate gyms around. New owners have really stepped up and made this gym a place everyone can enjoy and get a great workout in. The community is amazing and everyone's always so nice. Plus it's nice as a female being able to workout in a comfortable environment! They also just added more Bootcamp style classes, more personal trainers and a couple massage therapists!
