Three rounds for time of:
Run 800 meters
50 Back Extensions
50 Sit-ups

I did the full WOD. Time: 32:01. Calories: 358. First time ever on a treadmill, so as my skill and comfort level there goes up my time should go down. After slowly building up I did the first round at 7 MPH and the next two at 8, which got my HR up to 91%. The back extensions were actually pretty painful, but mainly in my glutes and back of the legs - the back was fine. Did the situps on a balance ball, and they were fine.

Out of curiousity I left my HRM for the walk home with the weighted pack (~1.5 miles uphill, 16# plus workout gear in the pack). 240 Calories in half an hour.
