Just posting an update on how the shop went. The class went a lot better than I expected. The location I went to had three times available for a class. A morning bird, morning, and evening one. I opted for morning bird for less distractions, even though I was told it's with a difficult instructor. Went through the tour and chatted with the instructor to pass the time and get settled. Not as many people.
It's definitely a different experience. You follow along to the music and can adjust the level of resistance. While it was challenging, you can go at your pace. It's like a gym, where everyone is doing their own thing, but the only difference is everyone is in sync to the music and don't have headphones on. The thing I enjoyed most was that you get real-time feedback from the instructor if you're doing something wrong or unsafe, on your form, posture, and technique. There's mirrors for you to see how to adjust.
Anyways, this shop is only worth it, if you were going to try out the class anyways. And looking for guidance to improve, and find an instructor with the right type of class and music. Might as well get paid while trying it! But if no interest in trying out the class, not worth it. The report itself has some narrative and sections, but not too bad.
