About this timer
A five-minute warm-up, five rounds of three minutes brisk and two minutes easy, then a five-minute cool-down. Interval walking is one of the most studied ways to build cardiovascular fitness in people for whom running is not an option, and the alternating pace is what makes it work — the brisk blocks push your heart rate up and the easy blocks let you sustain the session long enough to matter.
Best for
- Building fitness without impact
- Cardiac and pulmonary rehabilitation programmes, where prescribed
- Anyone returning to exercise after a long break
