A thirty minute walk three times a week is all it takes to lower your blood pressure and risk of heart disease. Even though some guidelines advise moderately intense exercise five times a week, researchers from Queen's University, Belfast, found that three brisk walks a week lowered blood pressure and reduced waist and hip circumference.
Researchers divided 106 people that rarely exercised into three groups. One group walked 30 minutes five times a week, another group walked 30 minutes three times a week, and the third group did no walking. While both walking groups showed decreases in blood pressure and lost inches, the non-walking group showed no changes.
The authors of the study hope that their results will help couch potatoes who don't exercise at all begin to exercise gradually, and those who feel they don't have enough spare time to exercise effectively to take those first healthy steps.
