Bring your gym clothes/ workout clothes to work ... with your sneakers. As soon as you are off from work .. change there before you even get to the parking lot. The outfit is half the fun right
. It is soooo much easier to talk yourself out of going if you are still in your work clothes. I also find that if I start off slow I will normally pick it up somewhere in the first ten minutes of my run or I will add extra miles on the back end. An object in motion stays in motion ... An object at rest stays at rest. You cannot argue with physics.
