Love this location. We have left to try other gyms and always come back. It's always clean and maintained. The staff is friendly which always sets the tone for the space. Casey H. is always so helpful and great when I have questions especially with the new offerings I'm getting used to. We love the new remodel! Keep it up, mountainside!

I'm so excited about learning about Mountainside fitness and all they have to offer from Chantel Griswold. She took her time explaining what they had to offer and was happy to help. I needed to reschedule my trainer appointment and no problem, she jumped right in and helped. People like Chantel make this a friendly atmosphere and make everyone feel welcome!
