This is not only an amazing gym, but an amazing community to be a part of! When I first started, both instructors and members made me feel so welcome and comfortable joining in on classes. They have a huge variety of classes and all of the instructors are so friendly and supportive! They continue to make changes and improvements to the gym based on member feedback. This gym is simply the best!

This wellness and fitness center will transform your life! Hands down, it is a phenomenal place to workout, recover, and grow alongside other community members. The coaches are significantly knowledgeable and are invested in your wellness journey. The classes are engaging and fun, and personal training sessions are beyond amazing. I do personal training with Frank who is FANTASTIC and I highly recommend him. Shout out to Colleen as well---I love her boxing classes which have also been a highlight of my SLS experience.

I've been a member of SLS Fitness for over 12 years. SLS is so much more than a gym, it's a community that feels like family. I've never felt intimated or uncomfortable as I have felt in other gyms. The Coaches/staff are amazing and are always watching out for you. Even in classes, you still feel like you're getting that special attention from the trainer. It's where everyone knows everyone and you're not just a number.

I started at SLS almost two years ago with encouragement from a few coworkers and have established that is in fact one of my best decisions ever. The atmosphere is amazing and welcoming. The classes are well structured and have great range from beginners to professionals with modifications if necessary. I absolutely love strength, boxing, and stretch. Definitely recommend if anyone was looking to join.

My partner and I moved to a new area and were searching for a gym to join when we stumbled across SLS. Fast forward, I've been a member for about a year now, and I can confidently say that I'm here to stay for the long haul. The sense of community at SLS is truly something special - you’ll find the support and camaraderie you need here. The coaches are EXCEPTIONAL. They are knowledgeable and encouraging, and they go above and beyond for the members. The gym is well-equipped, clean, and the atmosphere is always buzzing with positivity and motivation. Joining SLS has been one of the best decisions I’ve made, and I can’t recommend it enough!
