Before experimenting with a new diet or exercise regime, use this simple litmus test:
Does the person recommending the program look healthy?
A lot of fasters look gaunt, like they are about to die.
I feel like I could huff and puff like the big bad wolf and blow them over.
The same goes for marathon runners.
Marathon runners look like Gazelles.
Sprinters look like Lions.
Kings of the Jungle.
Life is actually much more of a series of sprints than a marathon.
The high performance coaches I follow teach that building physical and energetic strength is about cycling from period of significant stress to period of deep recovery.
Who do you want to be?
A roaring majestic lion or a gaunt, skinny twig?
