I take spinning classes sometimes but wanted to tell you not to use the same tape every time -- maybe at only one time slot a month. There's one instructor where she literally used the same tape every class. Boring.

As for the classes, usually there's a sprint song where you take turns sprinting or do it together as a class, a climb, a pyramid where the hard portions get longer then shorter, maybe an all standing song (but I can't finish those yet), and warmups and cooldowns.

You can make games out of it such as having people pair up and alternate the sprints, or doing it by rows, gender, color shirts, whatever.
