    Updated: I tried my best to be mindful despite reading the many reviews advising gym goers to be mindful but I pride myself in experiencing things for myself in understanding that everyone, and everything is different for different people. Unfortunately, I have become victim in the “Sarah effect”. I’ve noticed many excuses being made for her in the replies by the facility but I would like for you all to factor in, that everyone is not lying and someone has to be telling the truth if not all of us. From my experience this woman seems completely insufferable. Misinterpretations and confusions are natural, but what I’ve noticed is that when the confusing scenarios present themselves, instead of offering concern, mindfulness, and apologetic or affirmative action… she prioritizes her ego and chooses to combat and challenge. Most people in power are so disconnected with their emotional side that it becomes difficult for them to see people on smaller scales. Their use to dealing with so many people under them that there minds become robotic and it becomes difficult see yourself in someone else’s shoes or circumstances. I believe she doesnt feel subjected to the natural self awareness we all have to undergo as humans who share a world with different humans, so she continues to make the exact same mistakes. In her position, they are possibly just viewing the numbers she’s pulling in on a logistics basis and no one above her is seeing the need to accurately assess or modify her behavior if they are seeing the same numbers overall. However, her continued behavior of picking out certain individuals to verbally humiliate is not okay regardless, are indicative of the promises made by this company. She witnessed me signing up for a membership through my insurance, I even left a positive review about it, mainly for the trainer and the young man assisting. When arriving i stated extremely clearly that I wanted transfer gyms and the sign up would be through my insurance plan. She even overviewed the screen to make sure the young man was able to navigate through it accurately, and she overheard him asking me for a gym code, she was right there during the entire process. It was not indicated by the associate nor reviewed by her whether or not I was explained the specificities in checking in knowing that they differed from the regular process. Also, if I’m signing up to transfer locations and I’m being told at the end of signing up that I’m “all set to begin” why would I think that I was doing something wrong. My second time going to the gym, she was present, I scanned the badge believing it went through, and again, no one corrected nor felt a need to readjust my actions. I informed the young lady I was interested in a new orientation group, she said, “absolutely I can get you in at 5:30pm I just have to enroll you… come back up to the desk closer toward the time and I got you.” So this is two times she’s witnessed me attend the gym without specific detailing of how I should sign in. My third time entering however, she noticed me scan the badge. A sweet young lady looked at the screen but never looked back up to me to indicate anything. Before I can inform the associate that I had a one one one session, Sarah looks at her and instead of again, reconstructing the matter in a positive tone or manner, she says to the young lady “well if you won’t handle it I will” ! She looks at me (there’s clear confusion on uncertainty on my face due to her abrupt reaction), instead of her explaining or reassuring that everything was okay before detailing the minor issue she bypasses it and says “Look, imma need you to check in by name next time you decide to enter this gym because you’re messing up my system, and you keep doing it.” Remember,I’ve been there twice before and she was present both times and never thought to check in about it at those times, but she’s making it clear that she’s noticed it prior by specifying in her own words that I“keep doing it”. I’ve run out of space,but she continued to cut me off, be accusatory,and very dismissive.

    The tanning beds AND the floors in them are always dirty. Locker room floors are as well. I found dirty socks, a tag, and false eyelashes in the floor in the family locker. Whoever works in the middle of the night (it’s not just one person it’s every person that works at this time) is always no where to be found. I’ve sat waiting for staff for 30 minutes and walked around searching so I could use the tanning bed before. When I’m doing cardio I’ve seen a handful of people walk in and waiting at the front desk so long they just walk out (obviously they needed something) more than once. I’ve been there for three hours and not seen staff the whole time except briefly when I walk in. It’s always male stuff never noticed a female working these hours. I’ve come to the conclusion they’ve either left, doing drugs in the locker rooms, or fell asleep in the shower. I’m writing this review in the parking lot and from the time I walked in about two hours ago, haven’t seen stuff the last hour even from the lot still no one. This is actually the worst planet fitness I’ve been to, the newer equipment means nothing if the gym is filthy and stuff isn’t present. There’s better machines for the black card members in other gyms that Brentwood doesn’t have as well. I cannot believe I still haven’t seen anyone that works here this has been going on for MONTHS since I’ve been going to this location I’m sure it’s been going on way longer though. Probably the reason those kids tried to hold it up because it would’ve been easy. What is going on here ? So strange.

    I absolutely love the Brentwood location. It is very clean and welcoming. Sarah, the manager is excellent I left the Overland location because it was not accommodating and super cold in the winter time. I am so happy with the change!

    The manager Sarah "Elizabeth" is extremely unhelpful and rude with an out of town guest. Not welcoming at all. Patrons were also loud and seemed like an out of control environment.
