This is a great gym for all ages, I am 61 years young and everyone welcomes me. The boxing classes are my favorite thanks to Larry and Shawn , but Becky my PT IS GREAT. She is helping me to vary my workouts and get strong.

I have belonged to one gym or another since I was a teenager but this is BY FAR the best experience I’ve ever had at a gym. All of the instructors are outstanding. Owner Sherri Sarrouf has assembled an all-star team of fitness pros who teach excellent, challenging, fun and SAFE classes for all abilities and interests. Multiple classes run just about every 30 minutes and the daily schedule is jam packed with a variety of classes. If you miss one class, chances are there’s another comparable one taking place soon OR you can work out on your own in one of the two weight rooms.In every class you will meet people of all ages and fitness levels from beginner to advanced. The staff (and members I met so far) are nurturing and helpful as if you are all part of a big team. Members receive a daily email with class schedules and articles containing the latest nutrition and fitness news.Check their website to see the incredible variety of classes they offer. This is the perfect gym. You will not be disappointed.

Excellent facility. You will not find a better value in this area. Very knowledgeable and professional staff. You get a serious workout and you will be surrounded with good people who are serious about getting the most out of their workout. No judging or people sitting around using their cell phones. I have only been a member for 2 months and I love it. If you want to get the best in fitness and nutrition help, and you want results fast, this is the place to be.

Sls is an absolute gem. A class focused gym with 30-minute classes that are varied and whoop your butt. I've been a member for over a year, and I love showing up and not stressing about what I'll do when I get there, cause it's new every time. You can go hard in Metabolic Effect or Weight Room, get killer cardio with Spin or Interval Boxing, stretch in Recovery or Arial Yogo, and get physical in Boxing or Jiu Jitsu. Plus the other classes that I don't want to try and remember. If you're looking for classes, this is the best place in the area by far.

I've been coming to SLS Fitness for almost a year, and its an fantastic one-of-a-kind gym with a great fun owner, excellent knowledgeable, helpful trainers and a community atmosphere. This is a class-oriented gym focusing on 30-minute workouts, and trust me you'll get more bang for your time out of these 30 minutes than an hour on a treadmill! Sherri (owner) mixes up the circuit and metabolic effect workouts, so you're always doing something new. That alone is worth the membership, since they have the workouts already figured out, all you have to do is show up. No workout planing needed, the less thinking for me the better. The MMA classes are a nice change of pace as well. SLS also offers a Farmer's Market on Tuesdays, shakes and supplements on site every day. Members also get the benefit of free or discounted lectures from time to time. Day care on site for cheap is especially helpful for me with 3 kids. There is also volunteer initiatives for those who want to get involved. Like I said, its a great one-of-a-kind place!
