You'll probably consume three of the most common electrolytes; sodium, potassium, and calcium even without trying. Sources table salt, bananas, milk. Chloride is in tomato products and tomatoes also are sources of potassium. The others are quite common in everyday food types too.

You pretty much need to go out of your way to not consume any of those essential electrolytes. SI can't really imagine that strenuous exercise shouldn't deplete electrolytes unless it's for a really long period in hot conditions.
