Overview: A gym in a residential area of Tokyo offers classes for a slightly unusual activity where going backward is actually a sign of progress - doing backflips. These lessons are becoming increasingly popular among children, housewives, and company employees who drop by to master their technique after work.

For 3 days, we spoke to people determined to find out if doing a complete backflip will also help their lives take a turn for the better.
