Wonderful gym! Trainers are top notch, invested in other aspects of health, aside from physical fitness. The gym is always very clean, great equipment and a variety of classes for all levels of fitness. I would recommend anyone to go here!

The environment is bright, open and inviting. I was welcomed from the moment I walked in until the moment I walked out; everyone was incredibly friendly and gracious. I took a rowing class with Jordan, he was fantastic. I could tell he was extremely knowledgeable about fitness, but also about rowing. He was super helpful with technique (rowing is not my forte, but I do enjoy it). Also, given we are in covid, I must mention the gym was clean, Jordan was conciliatory to maintain social distancing when we had our masks off and everyone sanitizes their equipment thoroughly. Thanks so much for the workout SLS! I will definitely be back!!My only business suggestion is to put some signage on the building because you have a phenomenal space I think is being overlooked by some. I found your gym on the web, but if I was just driving by I would never ever notice it. I hope to see a huge sign when I return!! :)

I'm going to miss this gym and these people SO MUCH when I leave town for good next week. I'll do my best to find something exactly like it in my new city, but geez that's a high standard to match. SLS Fitness has been my favorite gym I've ever been a part of. :) Nothing beats the passion and quality of the instructors and the convenience, flexibility, and fun of the classes!
