Great post from Tabata Times:
Amen I say, especially as we start to get into CrossFit Games season. I’m always amazed at how many people go strict Paleo, etc. but then only exercise in the controlled environment of the gym. Get out there like your ancestors! Strike out into the woods in the snow! Swim in the ocean! Climb a mountain! Sometimes we forget the “learn new sports” aspect of the CrossFit philosophy. There’s no better “constant variation” than trying something you don’t know how to do.
