Locker rooms only have one bathroom but there are 2 showers and lockers to use. My friends and I have gone there to take the zumba class that is offered in the upstairs studio every Tues evenings from 6-7pm. It's an awesome class and the teacher, Rhyann, is fantastic!!! I am NOT a dancer and am NOT coordinated at all and definitely have no rhythm BUT I have sooooo much fun in this class that I don't care that I look like a total spaz jumping around the room! The music is energetic and uplifting and Rhyann has really fun routines for each song....AND it is a total workout! I am totally sweating and tired but full of energy after each class (she also teaches at our work gym)....she never makes you feel silly and is always encouraging. Rhyann also changes up the class by introducing new music/routines in so you are never bored...and she is always open to suggestions and ideas.....5 stars for the zumba class! Studio is a little on the small side so it's good for smaller classes, like 10 people, since you MOVE during class....but you have mirrors on 2 sides (since it looks like it's used for dance/ballet as well), so you can see every silly shaking move you make! So, I would highly recommend trying the zumba class out at least once...just to try it! I never thought I would love it as much as i do when I first agreed to try it with a friend :) You can also check out the gym while you are at it...but the zumba classes are separate from the gym itself so you don't need a membership to drop in :)

Iron Works is fantastic. Reasonable price and 24/7 access means you have basically your own…read moreprivate gym for less than 1/2 of what you'd pay elsewhere for crowded, unsanitary equipment. I get that some people hit the gym as a social exercise or to pick up strangers. Iron Works is for the opposite i.e. people who are private, don't need to show off or take selfies while squatting and value their workout time. Scott and team take amazing care of the facility and are always available to help if you need anything or have questions. Best place in Boulder, by far.

Incredibly disappointing experience with Iron Works. I signed up for a membership based directly on…read morethe pricing and terms outlined on their official website. As shown on their website under the Individual plan, it clearly states "Members must be 16 or older." Furthermore, they explicitly offer a "Student: 16-25" tier. Despite meeting these exact requirements, I was told that 16-year-olds cannot actually have memberships here. It is completely unacceptable for a business to refuse service based on internal policies that directly contradict the explicit terms published on their own website. Save yourself the hassle and go to a gym that actually honors its own public rules.

The staff here is so wonderful and nice, every single time you come in. All of them as well,…read moreespecially the big guy with long hair, he's like the nicest human being ever especially for gym staff that is usually pissed when they're even working at other places. This spot has plenty of equipment, only slightly busy/packed during peak hours of course as every other gym is, but honestly most days are fine even during those hours. Usually very clean (gym and bathrooms) but the steam room could do better! You can see the sludge in there and honestly just quick hose down every day with the right cleaning solution would do it, it has a drain so it's not too hard haha. Sometimes the pool smells horrendous haha like wayyy too many chemicals, maybe use local biz Mr Pool - they're amazing for pools indoor and out, as well as the hot tub. The music kinda sucks they play but it's generic gym music so you can't really complain. I love it here, they have a good sized area for everything you need. Maybe one more chest/back pectoral fly machine would be perfect!! That's the only one that's always taken. Cheap prices as well. Good trainers. I don't get how people give it bad reviews.

I have never written a review before, but this was by far the worst customer service experience I…read morehave ever had. It would be negative stars if possible. As someone in a management role myself, I have never encountered a manager as unprofessional, rude, condescending, and abrasive as Cherek. My friend and I came in at 8:00 PM to use the advertised 5-day free pass because we were genuinely interested in trying the gym. We filled out unnecessary paperwork about our personal workout goals and schedule (we weren't looking for personal training so this didn't need to be shared), took a tour with a very friendly employee, and then politely explained that we were not interested in purchasing a membership that night because we wanted to actually use the facility first. The kind employee warned us if we decline membership he HAD to bring Manager Cherek back over. What a joy that was. She immediately started trying to resell us on the pricing. I politely told her that changing the numbers wasn't going to change my answer--I wanted to try the gym before committing to a membership. Her response? She looked at us and said we "seemed tight on money." I was honestly shocked. What kind of manager thinks it's appropriate to make personal financial assumptions about complete strangers? That comment alone should disqualify someone from being in a customer-facing management position. Despite me declining multiple times, she continued pushing the pricing. After saying "no" for the third time, I finally explained that I'm already a CorePower member paying around $140 per month and was simply looking for a gym that offered different workout options and was considering a more affordable option. Saving roughly $150 over an entire YEAR wasn't going to convince me to buy a membership for a gym I hadn't even been allowed to try. I shouldn't have to share that information but was forced to so she would stop offering savings that I do not care about without getting to workout first. Then the conversation somehow became an INTERROGATION She repeatedly questioned why we were there, asked about our workout goals, how frequently we plan to come to the gym and when my friend said I don't know I just wanted to work out, she responded with, "Then why are you here if you don't have goals?" Because...we came to WORK OUT. That's literally the purpose of a gym. The irony was that after all this talking, we still hadn't been allowed to step onto the gym floor. Then came the best part. She told us we could only use the free pass if we scheduled another appointment with her so she could discuss membership again. We asked, "So you're saying we can't use the advertised 5-day free pass unless we schedule another sales meeting?" She confirmed that was correct and said we HAVE to set up a date time in order to use the facility tonight. So after spending ** 27 minutes--from 8:00 to 8:27 PM** --being pressured, interrogated, judged, and repeatedly told why we should buy a membership, we were sent away without ever being allowed to use the gym. This wasn't a free pass. It was a sales trap. If your "free trial" requires customers to commit to another appointment before they're even allowed to work out, then advertise it honestly. Don't market it as a chance to try the facility when it's really just a high-pressure sales pitch that was unprofessional and abrasive. I've visited plenty of gyms that are confident enough in their product to let people experience the facility before asking them to commit. This gym clearly isn't one of them. Save yourself the time and go somewhere that actually lets you use the free pass they advertise--and where management knows how to treat potential customers with basic respect.
