Haha, I have a treadmill, although I may look like I am a graceful being, let me assure you that I am quite the opposite. I can walk successfully on said treadmill but once I try to add speed I become one of those YouTube sensations that everyone laughs at, my clumsiness is the stuff that GIFs are made of.
I do wait until the temps drop a bit before heading out and I have my phone with me in case I actually cannot run back, someone can come and pick my sad ass up. The good thing about where I live is that it is never actually cold, so no matter what you are always running in the heat. If it is too hot I jump on the elliptical.
