Even Semi-Strenuous Has Benefits


A recent study published in the Archives of Internal Medicine supports the common sense notion that regular physical activity can reduce the risk of coronary heart disease in women even if they remain too fat. That is if physical activity levels reach 1000 kilocalories per week, or about the equivalent of 30 min of brisk walking on most days. However, "reduced risk" implys that some risk remained for those that remained overweight or obese. Risk appeared to be completely eliminated if moderate physical activity was increased on average to 45 minutes per day
