    Power Hour (Total Body)

    That was one of the best classes! Natalie is so encouraging and motivating and for it being my first time doing this type of work out I thought extremely comfortable. She explained all the moves well, and I really enjoyed the variety of exercises. We did a circuit

    The Ascent - L1

    Versa climbers are a crazy good workout! I thought there would be a larger learning curve but it was pretty easy to figure out and the instructor was super nice. It definitely requires a strong core to do the full workout but didn’t feel pressure if I had to take breaks. Burned 350 calories in 30 minutes so I’ll be back!

    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.

    Even though this class is built around progressions I always find a challenge at my level (I don't go regularly). The instruction is what I appreciate - real knowledge of kinesiology and customized feedback. It felt like most of the class were regulars but folks were mostly friendly and also offered encouragement.

    Im giving it five stars bc I genuinely like this gym very much. That being said, I do not like a partner workout. No two people are perfectly matched and it should really be an autonomous workout. Also, because there are no towels provided, and no mandate to bring one (though I do), all the equipment is drenched. Add to that the people working out barefoot, and it can get pretty dicey.

    My first time at a bounce class, and I had so much fun and burned so many calories. Class is split between cardio bursts on the mini trampoline, dumbbell arm exercises, and abs. Megan was very friendly, energetic, and made me feel very comfortable by explaining proper bounce format before class. The music was also great, and gave me the boost I needed to finish strong. The studio is located in the garage of a residential house, but very well marked and easy to find.

Simple gym, but in a good way. Can't recommend enough, the first class pass class I've done where I've considered getting a membership.
