To be healthy, you really do need to break into a sweat when you exercise, say experts.
According to BBC News Online, members of the American College Of Sports Medicine are concerned that official advice to do 30 minutes of gentle exercise each day is being misconstrued.
People should do at least 30 minutes of moderate exercise five days a week, or 20 minutes of vigorous exercise, like jogging, three days a week, they say.

There’s confusion about the ideal amount and intensity of exercise to improve health. All agree that regular exercise is essential.
The World Health Organization has said 30 minutes of gentle exercise each day could be enough to sustain a minimum level of fitness.
Recently, researchers at Queen’s University, Belfast, found walking for half an hour on just three days a week gave similar fitness and blood pressure benefits to walking for 30 minutes five times a week.
