    Incredibly equipped gym with the best array of machines and free weights. Not a bro gym but a…read moreplace for serious training

    I have only been to this gym twice but it's a cute little place right off Highway 297 outside of…read moreLongmont....the people seem nice and the gym is new so everything is nice and clean. 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 :)

    This gym is a little bit smaller than the others we have visited around the country, but it had…read moremost everything we needed to get in a good workout. There were several rows of cardio and the elliptical machines worked just fine. They do still have the 30 minute circuit equipment, but it's in the middle of the workout area, but still effective. They had several smaller side rooms, one with the new squat rack and weights so that's nice. They also had an abs and stretching room, but there isn't a ton of floor space for mat work It was very clean, they have a really nice lobby and black card area and staff were super friendly

Poor customer service i hope the place i go in future communicates better.
