I've Got Your Cardio Workout Right Here

Who needs a treadmill, track, or triathlon when you have this? The wind chill right now is -6. As in 6 below zero. Clearly I didn't make it to the sculpting class I was planning on. No worries. Snow boots instead of running shoes, a shovel instead of weights, and 45 minutes in below freezing weather instead of sweating inside a gym, and I feel fine.
