I have never been one to go to the gym as I never knew what I was doing and always felt like people were looking and judging me. That is until I was introduced to SLS Fitness. SLS Fitness has built up my confidence in so many different ways! I am happy to say I am down 30 pounds and that’s all from the support of fellow friends and coaches, the amazing classes and the friendly atmosphere. If you are looking for a gym that actually cares about you and your fitness goals don’t hesitate and come join SLE Fitness.

First time I’ve signed up for a gym. Staff are extremely friendly and great to work with! Billy and Olivia welcomed me to the gym in such a friendly manner which made it easy for me to become comfortable quickly.Coach Josh is awesome! He’s very nice and is willing to work with you to find the right pace tailored for you.

Nothing but great things to say about SLS Fitness. The culture of this place is what keeps me coming back.I work in sales where my hours are very long and unpredictable and it's often hard for me to go there consistently. Every time my wife goes in without me, she always comes home telling me that the staff was asking about me. It's this kind of personalized attention that you don't get at the big gym franchises. It's not overly crowed and I really enjoy groupy atmosphere. You can tell everyone is there for the same reason and you have unlimited support if you need it. If your looking to take your workouts to the next level, I HIGHLY recommend looking into PT (personal training) with any of their coaches. I've personally seen huge progress since I started it 2 years ago

I have been a long time fan of this gym but faced with Covid challenges they’ve taken it to another level and upped their game. The equipment is even better, staff is still great, the classes are well coached and their safety protocols are outstanding.

Absolutely hands down the best gym I’ve ever been to. Everything I’ve ever wanted, all in one gym. I’ve moved from Mass now, but would move back JUST for this gym. If they ever consider opening another gym, I hope they consider Raleigh NC!!! Miss this gym SO much. Loved the staff, loved the setup, loved the classes. All at a low price if you think about what you’re really getting. Wish they’d open one in Raleigh, I think about it every time I go to my gym here 😂 thank you SLS!
