An exercise "snack" is a short burst of movement – it can be 20 seconds or several minutes.
It could be a brisk walk at lunchtime, taking the stairs, or marching in place while you're waiting for your morning coffee to brew.
You don't even have to change into sneakers!
One study found that an "exercise snack" of just 20 seconds of brisk stair climbing three times a day increased aerobic fitness by about 5 percent after just six weeks.
And a review of several studies of exercise snacking found that these brief bursts of exercise resulted in significant benefits to cardiovascular fitness.
To fit exercise snacks into your day, try these Microsteps.
