I have been going to Mountainside for years. After trying multiple others, it is the best quality for the price. Always very clean and I rarely wait on machines.

This place is getting one star for this reason alone, I was a member 7 years ago at Mountainside. I left because of how expensive it was getting for a cheaper and competing gym EOS.
