The University of Washington in the US reviewed 174 studies since 1980 and concluded that doing SIX times more exercise than the recommended amount greatly cuts the risk of developing five killer diseases. World Health Organisation guidelines suggest a minimum of physical activity equivalent to twenty minutes of brisk walking a day.
However, doing six times that amount - two hours daily - can cut diabetes risk by 19 per cent, colon cancer by 15 per cent, heart disease by 15 per cent, stroke by 13 per cent and breast cancer by 4 per cent.
Two hours does sound a lot, but can be easily achieved. You can do cleaning, climb stairs, walk or cycle more. I hear the excuse of "I don't have time" and then you hear they have sat in front of the television for four hours that evening.
The study concluded: "any exercise is protective, but more is better" (naturally check with doctor first if you have concerns)
