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 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.

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.

Train with Lexie, Erik, Chris, Ken, Etc. they are all amazing to chat with and so full of gym knowledge! Built an awesome physic thanks to them, 4xed my chest/leg size, fixed my eating/sleep, gotten rid of lower back pain, & gotten my cocky manly confidence back! They are Great People & Great resources! I'm going to go hit a second workout at 8pm, just thinking about how great this gym is! Oh, and the regulars are the best! It's within walking distance of some homes/apartments & has some good eats around. Ok I could go on and on! 4.5/5 and 5/5 99% of the time!

Her knowledge of anatomy shows too; she gives these small cues in class that have changed an entire pose for me. She is not just giving a class, she offers guidance on life. In the over-saturated wellness space of Boulder County, it's my favorite studio. COVID-19 note: The one star-reviews listed here seem to me to be an effort to encourage the studio owner to change their COVID-19 vaccination policies. If I were in Colorado right now, I would respect THYS's current COVID-19 safety policies, even if it meant I couldn't come just yet; I know I'd be welcomed back in time, everyone will be welcomed soon enough.
