Which phrase in the passage is a prepositional phrase?
Burning Calories

We all need to burn off calories to help maintain a healthy body weight for our size and age. You use some calories simply without thinking about it in your day-to-day activities. How active do you have to be beyond that? There is no simple answer. The important thing to remember is that many people need to become more active than they are now, and you might be one of them.
