Anyone who's ever met me knows I'm no athlete. I mean, I'm a pretty active cyclist and rock a pretty mean game of kickball, but I have no idea how many pushups I can do, and have never touched a supplement, unless my daily vitamins count.
But, I am a huge believer in not sitting still. I learned long ago that moving around, no matter how little, can make for a whole different day. Stand while you work, take the long way, bounce around a bit while you cook and clean, and walk whenever you can.
In a grumpy mood? In that so-angry-we-can't-even-talk place with your partner? Move. It'll change. Seriously.
