I'm a relative newcomer to Flywheel, but I'm totally hooked. I don't have very much spinning or cycling experience, but there's always someone willing to help me get my bike set up to fit my body. This workout is intense - in 45 minutes, I've burned between 750 and 820 calories each time. The music is loud and some people are really advanced / intense, but the room is dark so you can focus on your own performance if you prefer.
The studio is clean and, given how sweaty people get, smells good and fresh. I forgot a water bottle one time and the women at the counter gave me one for free - thank goodness they did or I would have passed out! Everyone I've encountered who works here is friendly, welcoming, and helpful -- truly appreciated by a novice like me.
