Great place, never too crowded when I go. Literally never have to wait for the machine I want. Water fountain filter needs replacing? Replaced. Torn up benches? Replaced. Well kept gym.

You want to know what isn’t “awesome”? Slashing your hours by 30% and then claiming for the past 6 months this would only be temporary. Hmm, also having high demand equipment that hasn’t worked for the last 4 months. Really, you are risking verbal confrontation among your members by having only one or two working stair steppers without any limits on how long a person is on it.

This place was cool until they started not letting people wear their backpacks inside. It’s a gym everyone has a bag and has them with them. Really ruining the experience with them nagging everyday about leaving bags in car or in locker.

I enjoy coming here , I am always greeted with a smile . I see employees cleaning equipment , they always correct issues ie being out of paper towels or bathroom stocking issues .The only complaint is the Wi Fi needs to improve can’t even sign on , hard to work out without tunes .

Would definitely not recommend, Who ever tries to bring their gym back to the floor will get told to leave it in their locker or car or if not prices will be going up🥱 like excuse me ? Since when was that a rule? It’s a gym people bring extra waters, their OWN equipment and carry personal belongings etc . And prices going up just so we can have our backpacks on the floor? Okay this ain’t no Chuze or Vasa or spectacular gym . Will definitely be canceling membership or just going to a different pf. Ridiculous.

Went in this Saturday to workout.I did not feel welcomed. I felt very uncomfortable while working out, a female worker with a hat kept on walking around the gym observing everyone. Not to sure what she was observing but it was very uncomfortable, I had to leave. Not so a “no judge mental” gym

I'm in and out. Nobody bothers me. People are friendly but equipment is pretty worn. Perfect if you're serious about starting your fitness journey and not worried about making the place a spa or rec center.
