High-intensity interval training alternates short hard efforts with recovery periods.
Why HIIT matters
It can improve cardiovascular fitness efficiently, but its high fatigue cost must fit the wider programme.
A practical example
Completing six hard bike intervals with generous easy recovery between them.
Common mistake
Calling any circuit HIIT or performing maximal intervals too frequently.
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.
