Fire gym- I've been coming here for 3 years. The equipmrnt is very nice and so are the people around. I love this gym, it's like a second home to me. I've been coming here everyday after school. I used to get bullied and the gym helped me boost my confidence and become a better person overall.

I am giving a shout out to Sarah Rogers at Mountainside Fitness. She was super helpful in setting up my membership. Folks, reach out to her for signing up and she is fantastic.

My favorite gym out of a couple different locations I've been to. The gym layout is perfect. Staff is always friendly and the place is always nice and clean.

Corporate structure is predatory and does everything and its power to make it difficult for people to cancel memberships. Beware of training contracts as if you ask to cancel training they may have you sign a hold document instead and then immediately start charging your card again after the 30 day hold expired. Three months of training charges occurred on my credit card and when I ask for a refund, none was forthcoming.

They sent a text to my daughter.as shown below from Taylor Hunter . My daughter called the number and they were asking her for membership money as our card had expired. I thought when I wrote the letter in April the membership stopped in June. I called Taylor and the corporate to let them know I was never told it now has t... read more

I have had many problems here recently regarding the staff. Recently Danielle has been verbally abusing her staff and the people trying to work out and mind their own business. She has also recently yelled at me and my friend for letting him in the cold plunge so he could test it out and see if he wanted to get one. She threatened to cancel my friends and my own membership.
