A fitness challenge has been issued at work between day, swing and graveyard shifts. Five competitors from each shift will do the Cro$$fit "Cindy" workout - 5 pullups, 10 pushups, 15 air squats, as many rounds as possible in 20 minutes, with the goal of 20 rounds. We have four weeks to prepare. My first go at it wound up with 7 rounds in 8 minutes and almost going for the bucket, but too wiped out to puke. Bring. It. On.
