On a hot day in the mid of July, the idea was born during a long car drive.
We were thinking about the challenge that we would always fall back on the same sets of exercises when training. Brainstorming and iterating on this idea, we came up with a couple of ideas like building a huge library of exercises, supporting the user to build custom workouts by smart training patterns and suggestions, and using gamification elements such as performing duels with your friends.
