After two days of the tightest hamstrings I've had for two years, I went back to work ... 10 clean, squat, press + 10 bicep curls + 20 tire step-ups (better tire) + 10 pull downs (x) + 10 rows + 30 jacks + 10 DB press + 20 squats + Every two rounds, 10 sprints.
I ran faster today and it felt good to just go get it done. I asked if six rounds was enough. They laughed.
Tuesday's challenge should be harder.
