“Any exercise is better than no exercise,” says Dr. Kelly Brownell of the University of Pennsylvania. Sports medicine experts usually claim that a person needs to exercise for some minimum period of time, usually a half-hour a day, three or four days a week.
But this puts a lot of people off, and they end up not exercising at all. Do you feel like taking a five-minute walk this afternoon? Or maybe a bike ride around the block tomorrow? These activities are small but definite steps toward losing weight. And who knows? You may feel more ambitious further down the line.
