If you’re a consistent gym rat then Mountainside is the gym for you. Sure there are less expensive gyms, however Mountainside gives you the most value for your money.

Mountainside Fitness is clean, family friendly and they have amazing customer service. They are the best value around. They are full service with over 80 classes a week and towel service included. The locker rooms are like a country club. They have new, updated equipment that’s well taken care of. Their childcare is amazing with lots of options and the sweetest girls watching our babies. You can’t beat their price for their offerings.

I started working out again after major back surgery. Im a lil older and was very self conscious hoping but didn't ask for a female trainer.

Brady truly is the best!!! He's very cautious of my back, but still works me out hard & challenges me. He truly is a great trainer and a great person inside & out!! Thank you Brady for all you... read more
