Denver mayor hurts himself while trying to do Ray Lewis dance

Dancing is also bad for you, as is stretching or doing calisthenics of any kind. Warming up is for Krispy Kreme donuts. Before any physical activity, the only preparation you really need to do is to select a physical activity. Do not lift weights while running, is what I'm saying. Or do it. I don't care.

The mayors of Denver and Baltimore had one of those mayor bets on last week's Ravens-Broncos game. The result meant Denver mayor Michael Hancock had to perform Ray Lewis' signature intro freakout. He made the mistake of warming up:

The mayor's spokeswoman Amber Miller says he was hurt "during pre-game warm-ups."

Hancock is "expected to be on the field in the second half, ready to carry out the game plan and fulfill his end of the wager," she said.

Never, ever warm up. By the time you finish tying your shoes, you should already be in a full sprint or already buckling under the pressure of more weight than you can lift or on your third spin through the Ray Lewis dancebook. The clenching means it's working. Train like you care.
