SLS is a business that you can trust! I’ve been going to the gym for about 8 years now, and the management and coaches are amazing and care about their clients. I learned especially during the past two years with the pandemic, that SLS does everything in its power to keep its staff and clients safe and well. I can’t say enough positive things about this gym and encourage anyone interested to check them out.

From the environment, to the coaches and the great variety of classes what more could you ask for? SLS is not just a gym, it's a great community, coaches know your name and support as well as guide you through a workout to make sure you get the best out of each class. I was never one to go to the gym regularly but now I look forward to each week. Thank you SLS for all you do!

Award winning for a reason. The staff truly cares about you and your fitness goals. This space is special and there is a true community feel from the trainers and from other members as well. Classes are excellent, or come in and do your own workout whenever you want. Everyone has 30 minutes to invest in themselves and this is the gym to do it in.!! Hope to see you in class!

Being a member at SLS has changed my whole outlook on fitness and nutrition and even how to breathe to relax the nervous system. The coaches and staff are awesome and well versed in all areas. They are patient and help modify all the moves so that everyone can feel comfortable and be successful. I love to take a weekday class regularly on my lunch hour as I work less than 10 minutes away. I will never take a job that is too far from SLS! Also they have great sauna packages to detoxify and aid in recovery after a workout. There are lots of great instructional events and programs as well as private training sessions that have been beneficial. Love this place!

SLS Fitness has so much to offer everyone. Most classes are 30 minutes so I can fit it into my busy schedule. The classes are challenging and the coaches are all great at offering modifications when needed. The members are welcoming and supportive and I never feel intimidated even when I'm in a class of people who are further along on their fitness journey than I am. My personal training sessions with Coach Donny have truly been a game changer. I would suggest SLS to anyone whether you're a beginner or a seasoned athlete.

Best gym ever! I have been a member for over 8 years and never want to leave. The trainers, facility, classes, equipment are all fantastic. What really keeps me coming back is the community! I have never been to gym that was such a supportive and fun environment. The trainers get to know you, the other members are friendly, and there is always something going on a fundraiser, a special class, a seminar, etc. It truly makes going to the gym an enjoyable experience!

I joined SLS about 3 months ago because I was bored with my old routine. The variety of classes at SLS means I always have options. The staff have all been super welcoming and know their stuff. If you’re looking for a place to workout that doesn’t have the big gym feel this is it.

I have been a member of SLS for the past 7 months after being recruited by a coworker. Switching from one gym to SLS was the best decision I have made. SLS is a family atmosphere where each coach gets to know you personally and ends up feeling like part of your own family. Not only are the coaches invested in your weight loss or healthy life changes but the fellow gym members get to know you as well and help each other out. The staff at SLS are all amazing and super helpful if you don't know where to start at the gym. I highly recommend SLS fitness to anyone looking for a gym to start getting healthy or just wanting to build some muscle tone.
