    Power Hour (Total Body)

    Great class! The only suggestion I’d have - the instructor started going over what we’d be doing in class while we were still warming up. Her voice is on the softer side so it was hard to concentrate on what she was saying and do jumping jacks.

    Candlelight Vinyasa

    Makayla is such a wonderful instructor. Class was challenging and felt more like a power vinyasa. Great flow and music. The candle lit aspect is kind of an afterthought as it’s held in the HIIT studio but absolutely will be back.

    Flywheel: Method 45 - HIP HOP EXPLICIT

    I found the resistance and RPMs that Jason suggested to be incredibly unrealistic. But that being said, I got my second best score of all time, so maybe that was motivating?! Good mix of time sitting in the saddle and in 3rd position, as well as hills and sprints. I'll be back for another of Jason's classes.

    Best instructor I have had thru Endorphin, she actually went up to new faces before class and asked if anyone needed help with the bikes and such. The other 2 instructors I had at Lowry never bothered to make people feel welcome. great energy and a great sweat!!

    I loved this studio. They are so inviting, welcoming, upbeat, and helpful from the moment you walk in. The gym is clean, and state of the art. The class itself was a perfect mix of cardio, and strength, ending with a yoga cool down. Exceptional experience all around. This is the gym I would choose to purchase membership if I didn't use ClassPass.

    Olympic Endurance

    Great bootcamp & circuit style class. Main critique is that the class didn't actually start until about 11:20-11:30a (original start time listed at 11:15a). As a result, our ability to finish all the circuits and stretch was cut short. Please start on time so we can get the most from the session.

    Didn’t realize until after I’d arrived and hunted for the address a bit that this class is outside, and obviously not running today since we were in half a foot of snow. I even called the number beforehand to confirm it would be running but got voicemail and my call wasn’t returned. I would’ve appreciated a cancellation notice so I could’ve made alternate workout plans.
