At a glance: A straightforward guide to sustainable aerobic exercise, intensity and recovery.
Begin with a repeatable effort
Brisk walking, cycling, swimming or other rhythmic activity can improve aerobic fitness. Start at an effort you can sustain and gradually build duration.
Use the talk test
During moderate-intensity activity, you can usually talk but not sing. This can be more practical than chasing a precise heart-rate number, especially when medication affects heart rate.
Add intensity carefully
More vigorous training may suit some people, but it is not essential for getting started. A sensible progression balances harder sessions with easier activity and recovery.
Take symptoms seriously
Chest pain, faintness or unusual breathlessness are reasons to stop and seek appropriate medical assessment. Existing heart conditions may require an individual exercise plan.
