With a busy teaching schedule, fitting in the Surgeon General’s recommended 150 minutes of exercise each week can be a struggle. So is it better to do one long session every day, or a few shorter ones? According to a 2012 study, it’s more beneficial to take three 10-minute walks throughout the day than one 30-minute walk. Blood vessels become less stiff after exercise, so dividing your workout into smaller bursts creates additional opportunities for blood to flow more freely, thus lowering your blood pressure.
