This is a tricky one. Although writing is important for writers (LOL) excercise is too. It creates feel-good endorphins (Always useful). It promotes a clearer mind (Definitly a plus). It tones flabby muscles (Extremelly beneficial during the swimsuit season). And it helps us squeeze back into our clothes after the holidays (Really don't feel like buying a new wardrobe for the new year). So even with all of those fabulous, incredible, life-altering bonuses, I am still sitting at my computer writing, not even doing butt clenches, but hey, my fingers looks great.
I'm thinking a treadmill or elliptical with a laptop or iPad attach device needs to be invented, and still I wonder if I'd use it.
Would love to know what you do to keep up with your writing and keep your heart rate up at the same time.
