I know a lot of women who LOVE spin class. But I don't think they're doing anything like THIS!
These cycling instructors are teaching their students to do some wild moves on their bikes!
Olena Sheremet is a cycling instructor in Ukraine and teaches the most intense spin class I've ever seen. Remarkably, she says no one has been injured learning the stunts. Sheremet says the workouts are so intense, each hour-long class can burn up to 700 calories.
