Pushing it

April Calderon recently pumped out 61 pushups in 60 seconds while balancing precariously on three medicine balls, a feat that has been submitted to Guinness World Records.

The key is "great balance, mental toughness, and lots and lots of practice," said Calderon, a general manager for three Anytime Fitness gyms in central Florida. "But I'm really sick of pushups right now."
