A commonly used label for steady aerobic exercise performed at a relatively easy, sustainable intensity.
Why Zone 2 cardio matters
It can build aerobic capacity with manageable fatigue, although exact zone systems and device estimates differ.
A practical example
Cycling at a pace where breathing is elevated but conversation remains possible.
Common mistake
Obsessing over a single heart-rate number or ignoring medication, heat and individual response.
Keep the context in mind.
Training and nutrition terms describe general principles. The right exercise, intensity or food target still depends on your experience, health, goals and schedule.
Personalised coaching
Apply the principle to your own training.
A definition is useful, but your programme still needs to match your experience, schedule, recovery and goals.
