How much exercise is enough? Well, that depends on who you talk to. And everyone seems to have a different theory.
Years ago we were told that 30 minutes of light exercise several times a week was enough to keep the average person fit.
But more recent studies suggest that we need at least thirty minutes a day of brisk exercise. Another report by the Institute of Medicine recommended nearly twice that amount – 60 minutes a day of moderate to intense movement.
So who do you believe?
The fact is, there’s no magic number. Too many factors are involved to come up with a one-size-fits-all formula.
The key is to know your body, and to learn what it takes to keep in shape. If you find yourself gaining a pound or two a year, it’s time to adjust – both your diet and your level of activity.
Listen to the experts, but more importantly, learn to listen to your own body.
