At one point, this gym felt like a safe and professional environment for its clients…read more Unfortunately, that atmosphere has significantly declined over the past month. I was placed in an extremely uncomfortable and inappropriate situation by one of the trainers, Cynthia, who involved me in ongoing personal drama that should never have extended to a paying client. As someone who comes to this gym expecting professionalism, discretion, and a safe environment, I found the situation deeply concerning. What was even more disappointing was the lack of action taken by management. When I brought my concerns to Jason, the gym manager, and requested preventative measures to ensure I would no longer be subjected to this type of environment, I was told the situation "had nothing to do" with him. As management, protecting the experience and wellbeing of clients absolutely should be a priority. I escalated my concerns further through my trainer to the owner, only to feel dismissed and treated as though my concerns and experiences were invalid. That response was incredibly disheartening. It is truly unfortunate to see the culture and professionalism of this gym decline to this extent. Clients deserve to feel protected, respected, and comfortable in the environment they are paying to be part of. The owner has now decided because I'm voicing concerns that could harm the rating of the business to void memberships versus addressing the issue at hand.

I hopped on a Precor treadmill and tried to connect my iPhone. No luck. I asked staff on the floor if there was an app. No one knew. I went home and did a quick Google search. Precor uses the Preva app. Downloaded it. The app immediately asked for a club code. I called the Chandler location. Spoke with two people. Neither knew what I was talking about. I called two other locations. Same result. I finally spoke with an assistant manager. They checked with the general manager. Still no answer. Not a single person knew that Precor even has its own app. That alone was surprising. What happened next was worse. The assistant manager told me to call corporate. I did. The person who answered had clear attitude, no answers, and no idea who could help. I was then given the phone number for a local Precor sales rep. That is not a support experience. That is a handoff. I am writing this from two perspectives. 1) As a club member, this was frustrating and disappointing. 2)As a business consultant, this is exactly the kind of frontline failure I would escalate to ownership. You promote premium equipment, but your staff is not trained on basic features members actually use. You promote friendliness, but the experience felt indifferent, plus corporate attitude. You promote community, but new members are left to figure things out on their own. Mountainside Fitness started with smiles and towels. Somewhere along the way, the smiles stopped meaning much. (P.S. gave two stars because the physical gym is nice, equipment is good. But then again, that is the entry level expectation that every decent gym has. Customer service is the differentiator)

They are very helpful and make sure you're doing the exercises correctly. They also change it up all the time so that you're not bored or doing the same thing over and over. It's a good HIIT workout, and I always burn at least 300 calories in the 40 minutes of exercise, which is great by my standards. I would have given this place 5 stars, but then something happened (I thought about 3 stars but thats not fair to the rest of the employees). Toward the end of my 2 week trial, I took a look at my finances and even with the discount, it just wasn't doable. This place is expensive (more than other HIIT gyms Ive been to in the past) and being that I am not rich, I just can't make it work with upcoming bills, car repairs and everything else I have going on. When I called and spoke to Sunny, I explained to her that I unfortunately needed to cancel for now. She asked for any feedback for the program and I told her LOVE the classes, but I just can't afford it. She then said, in an incredibly rude tone, "did you know that before you signed up to take our free classes or did you just figure that out now?" Honestly I was shocked. It was so rude, it really hurt my feelings and it felt like she was accusing me of being a scammer or something. I would hate for anyone else to feel this way should they have to cancel. Also because of this I will not ever return, even if I could afford it. It was unbelievably rude. I shouldn't be made to feel bad for giving something a shot and just not being able to afford it. Guess I should have lied and said I hated it or something.
