Friendly, qualified, experienced trainers. Classes to suit varied fitness goals. A gym with a big heart for helping others. A gym for everyone...all ages, all levels of fitness. No obnoxious showboating at SLS...just regular people looking to be healthier. Clean and safe.

I’ve been a member for over a year now and I can honestly say it is the first place I never quit going to after a few months. It’s not a typical “gym” it’s a fitness center with so much more to offer. The coaches and staff are also amazing and always very helpful. 💪🏼

This isn’t just a gym. It’s a community of passionate, caring, like minded people helping each other be the best they can. Wish I discovered SLS years ago.

Family like environment, and they are always making constant upgrades to benefit the members. Classes for all levels of fitness, and trainers that challenge you daily. A unique environment that cannot be replicated.

SLS? More like BEST-LS! I basically live here part time because the people are nice and the classes are addicting.
