"Indoor cycling is by far my favorite group workout. A longtime SoulCycle devotee, I was hesitant to give Flywheel Sports a try, but I'm so glad I did! The popular East Coast studio finally made its way to San Francisco, and in the first week alone, I've gone three times. Unlike other indoor cycling studios, you're able to track your ongoing progress in a measurable way. A small machine is attached to each bike that measures your torque (resistance) and RPM (speed), and at the end of each workout, you're given a score that closely relates to these two metrics. During class, the instructors also let you know exactly where your resistance should be ("Turn your torque to 25," for instance), which I appreciate much more than the ambiguous direction of "turn it up" that you get in other studios. It's been nice to see my number grow with each class, and it really motivates me to top my score each time." — MF
