This gym is unlike any facility you've ever gone to. From class-based strength and boxing classes to open gym, there is something for everyone at SLS. The coaches and the member community are top-notch. I have been a member for just over a year and it has changed my life.

I moved to the area in 2020 and had been searching for a gym to call home. After two brief memberships elsewhere I decided to give SLS Fitness a try. As soon as I walked in I knew it was what I had been looking for. Everyone is so nice and welcoming (shoutout to Billy!) and it has everything I need. The 30 minute classes are perfect for my hectic schedule and if I can't make a class I know I can pop in and use the open gym. They also offer a variety of class types so that you'll never get bored.

What's not to love? ... its not just a gym where everybody does their own thing - its a community of friendly people who always motivate, help each other but people take an interest in each other's lives... regarding the club? - the trainers are great, there's a wide variety of classes and staff is not only very helpful but quickly resolves any issues... come by & check it out, you will love the atmosphere and definitely want to join!
