Humans don’t improve exponentially; our skills and talents take time to develop. When it comes to fitness, there is often a hard (physical) or soft (priority shift) limit to our growth because we can no longer put in the time and effort improvement requires. The phrase “1% better everyday” isn’t about literally improving 1% every single day, it’s about putting in the concentrated and meaningful work to get better. It encourages people to build habits and routines that will lead them to long term success.
