Less is More?

1 03 2010

Don’t you love it when health experts tell us that we need to spend less time exercising?  This good news comes with a warning: consult your physician before starting any new physical activity.

Interval training is 45 minutes of short bursts of intense exercise a week. This takes the place of the 2.5 hours of weekly exercise recommended in Britain and the U.S.

Will it work on middle-aged people who sit at a desk all day, or will it just give us all heart attacks?  More studies are needed.
