I've got my sprints to keep me warm

Amidst the ice-storm:
4x(110yd stride uphill, jog down
110yd sprint uphill, walk down)

Back indoors:
25 burpees, 25 crunches

I was going to do more inside, but got invited to dinner out at the last minute. The strides were similar to sprints, but with a focus on exploding from each leg. For sprints, the focus was covering ground as quickly as possible...obviously!
