"The list below shows you activities that will burn 150 calories. If you undertake any of these activities five times a week, you’ll burn 750 calories, enough to start realizing health benefits. If you do two of these activities every day of the week, you’ll burn a little over 2,000 calories per week and reap a health bonanza. (These figures are based on a body weight of 150 pounds. If you weigh less than 150 pounds, it’ll take you longer to burn the same amount of calories. The opposite is true if you weigh more than 150 pounds.)"
