What People Are Saying

"I like the location and the staff is very friendly and professional. I was impressed with the quality of equipment and my trainer was the highlight, indeed!"

"Everyone is friendly and is knowledgeable. I like the classes and variety. The training package is great (train 2x per week and don't pay membership fees to use the gym). I recommend your gym to everyone!"

"I've belonged to at least 4 gyms in the past 10 years, and this gym is by far the best. The atmosphere is great - very clean and at times I feel like I'm working out at my very own gym. The locker room is also very clean and I never feel uncomfortable there."

"The staff is friendly, I love getting a hello when I come in and a "Have a nice day" when I leave. Its personal and I feel like I actually joined a place that I can call my own."

"Other gyms should strive to have the appearance, staff, wealth of knowledge and most importantly, personable atmosphere and friendliness that you all provide here."
