If you want to sweat, the desert is still the place to go.

For the fourth year in a row, Phoenix has been named America's sweatiest city by Old Spice. Las Vegas came in second, and Tallahassee, Fla., placed third.

Old Spice said its findings are based on computer simulations of the amount of sweat an average person would have produced walking around for an hour during June, July, and August of last year.

Residents in Phoenix pump out an average of 26.4 ounces of sweat an hour during the summer, company research found. That's the equivilent of more than two cans of soda.
