Hector, I always explain the rules as a man in the fist meaning he's running back to camp. The phrase "running man," which I repeat several times like a mynah, sticks in their heads, and they know the man in hand means they're leaving the cave.
Whatever works for you -- just be sure to tell people that you're playing the opposite of the rules in case they encounter others who play the game.
Don't worry. I always explain what is in the rule, and let them choose the best way for them. I can add that I ask them to start with their hands under the table, or behind their back before showing their fist.
