"Change up" is an expression that is commonly used in baseball, but it can also be used in everyday conversation. In baseball, it means to throw a pitch that is different from the ones you have previously thrown, in order to surprise and confuse the batter. In everyday conversation, it means to switch things up, try something different or introduce a little variety to something that has become routine or monotonous. For example, you might "change up" your daily routine by taking a different route to work, or "change up" your hairstyle to try something new.
