    I look forward to Tuesdays because of Natalie and this class! Great workout, I like the option of heavier weights so that we can be challenged and she mixes up the style of Circuit every time so we never get bored! Thanks Natalie!!!

    Brandon executes a killer spin class. Amazing EDM music that you ride along the beat to! Its also nice because you hold sprints and jumps longer to really feel each muscle burn. A must if you like spin, cardio, or a fun workout!

    Fun workout! Plenty of parking. Been to several F45 and I have zero complaints about this one. IMO F45 is more suitable for people who already have the basics down since it’s not as hands-on as some other gyms.

    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.
