The Joys of a good Excersise

So I've never been a big excersiser... actually I've usally been quite the opposite. However I love my excersise time now. I find myself wanting to excersise longer (because of this I have changed my 45 min 5 days a week to 1 hour everyday!)! I feel like I have so much more energy, and I've really just started...I find at work I can't sit still anymore, I have too much energy to sit still... I'm going to be ADHD soon!
