Frequently Asked Questions

What is the difference between aerobic and anaerobic exercise?

Aerobic exercise is moderate and sustained, so the body has time to burn fuel with oxygen — jogging, cycling, swimming. Anaerobic exercise is short and intense, so the muscles work faster than oxygen can be delivered — sprinting, heavy lifting. Aerobic builds endurance; anaerobic builds power and strength.

Is walking aerobic exercise?

Brisk walking is, provided it lifts your heart rate and you keep going for a stretch of time. A slow stroll to the shops usually is not, because the effort never rises enough to challenge the heart and lungs.

What is the difference between aerobic and cardio?

In everyday gym use they mean the same thing. Aerobic is the physiological term, describing exercise fuelled with oxygen; cardio is the informal shorthand, named after the effect on the heart.
