The typical American fitness attempt is 6-8 weeks long every 1-3 years at an average of 3-5 hours per week. That’s as little as 18 hours (1,080 minutes) up to 120 hours (7,200 minutes) per 3 years at MAXIMUM.
Instead, I recommend creating an ongoing practice of 10 minutes per day, 7 days per week, no matter if you’re busy or sick or demotivated. People can always do MORE. But they should have a basic minimal practice. This puts people at 10,950 minutes (182.5 hours) at the end of year 3 at MINIMUM, if the practice didn’t grow at all.
I always aim for people to develop consistency PAST the 3 year mark, such that we can increasingly predict that they will trend AWAY from American averages (which are abysmal).
In the average scenario, each break in consistency results in a minor to major withdrawal of the benefit gained. In the 10 minute practice, there is a fairly linear progression indefinitely. Thus, it isn’t simply that scenario two is superior by 50-900% in total minutes; it is superior by magnitudes more than than, given that there is compounding of benefit. And that’s even if we never grow beyond 10 minutes.
I call it the compounded interest of physiology. People always want dramatic changes and programs; but there’s no staying power to those.
The tortoise and the hare was meant to be instructive.
