Does Exercise Have to Be in the Gym? 2019 College English Test 4

'Exercise is all about the gym for some people. But it doesn't have to be. Exercise is any form of physical activity that gets your heart rate up and makes you sweat. It can include everything from brisk walking and dancing to playing basketball and swimming laps. The key is to find something you enjoy and make it a regular part of your routine.
