#

OPM Databook was a physical fitness journal inspired by the famous One Punch Man workout routine - 100 push-ups, 100 sit-ups, 100 squats, and 10km running every day.

The Concept

A tangible tracking book for the simple, memorable routine. Log daily progress by hand, build streaks, and work toward becoming as strong as Saitama with the satisfaction of pen on paper.

What We Learned

Physical products require upfront investment in printing and inventory. The niche audience (anime fans who also exercise) was smaller than anticipated, making unit economics challenging.
