Death by burpees
With a continuously running clock:
Don't be deceived by the first few (easier) minutes - as the minutes go by, you have more burpees to do and less recovery time. I was able to get through the 11th minute with a few seconds to spare. I probably could have kept going at least one more minute, but it was time to start getting ready (and I was spent)! Take the FitYaf challenge - start with pushup burpees and when you can't continue with them, switch to regular burpees!
