Aerobic and anaerobic exercise describe different ways your body meets the demands of activity. Both can have a place in a balanced routine.

Aerobic fitness

Aerobic activity is steady movement you can maintain for longer periods, such as easy walking, cycling, or swimming.

Anaerobic fitness

Anaerobic efforts are shorter and more intense, such as a brief hill effort or a set of strength exercises, with recovery between efforts.

How to use both

Start with regular easy activity, then add short higher-effort work gradually when you are ready.
