The annual American Heart Association program aims to get people walking for 30 minutes a day, with at least some of that walk time happening during work breaks or lunch. Exercise physiologist Steve Sanders says regular exercise is a key factor in cardiovascular health. He says even fitting in short sessions of walking for five to ten minutes a day for people who are inactive, and accumulate two and a half hours a week is a great goal. The American Heart Association provides tools online to help people plan a regular walking program, and there are materials for employers to promote walking at workplaces at start walking now dot org.
