In honor of Spartan Fit Week, we’ve teamed up with Spartan Race founder and CEO Joe De Sena, for workout and diet tips to get you fitter than ever. Yesterday, we challenged you to go the whole day drinking nothing but water (yes, that means no coffee).
Today’s challenge: fast for a day. “That means no food, nothing but water,” says De Sena. “Maybe not during it, but you will be happier… and I guarantee it you will do it again.”
