The 3, 7, 15 scale.

I have a coaching rule-of-thumb about the amount of physical training required for success. Over the long run, it's an uncannily accurate predictor of success.

It goes like this:

  • Maintain fitness = 3 hours per week
  • Build fitness = 7 hours per week
  • Prepare for major event/elite athlete = 15 hours per week

Over the long run, the 3, 7, 15 is an easy 'pulse check' to see how many hours we are investing in the fitness bank. 

It's halfway through the week. Where are you at?
