No Pain No Gain
I just told my coworker that I am going for a run this evening, to which he responded, "you're crazy, its like 10 degrees out." I responded, in my mind, "that's some weak sauce." Don't let being uncomfortable temporarily slow you down. No pain no gain has never been so real....just kidding, but it still does apply. So get out there, breath in that cold - crisp air, feel it in your lungs, and do your body a favor.
