Not How I Remember Saturday Mornings

We have been calling the 10 circuits of 10 Push-ups, Crunches, and Squats the 300.
To crank it up, I added a 440 before and after (to also help on my 10-minute mile goal) and also sped up the circuits by following the Tabata Protocol - the sets take about 20 seconds and I rested 10 seconds in-between.

The circuits weren't too bad (may split them 5 and 5 next time), but the last 440 almost finished me.
