Some days I can fit in only a walk. Will that help my fitness?
Yes! Especially if you get up from your desk or couch to go for a walk – which obviously burns more kilojoules than sitting.
On your non-running days, aim to take 3 to 6 minute walk breaks throughout the day.
If you want to increase the kilojoule zapping, insert 5- to 10- second segments of easy running every minute to rev up the exertion level with little fatigue.
The bottom line: any activity counts – as long as you’re out there doing something!
