Healthy heart Start walking

If you hate getting sweaty, be reassured by research suggesting that walking can be as effective in reducing cardiovascular problems as more vigorous workouts. Walking two miles a day reduces heart attack risk by almost a third. Aim to walk briskly for at least 2½ hours a week. In a study reported in a US medical journal, women who did so gained as many benefits as those who devoted the same amount of time to more aerobic forms of exercise.
