Despite decades of being told about the benefits of exercise, I had absolutely no idea what the actual time investment looked like to go from unfit to fit. I couldn't put a number on it, and part of me assumed it must be enormous otherwise, why wouldn't anyone just say the number? Then I discovered Couch to 5K: 30 minutes, 3 times a week. A concrete, achievable number that delivered (to me) mind blowing results.

How could it be so low? How could i not know this? How is anyone walking around ignorant (as i was) of this?
