Today is National Start Walking Day. Not only can regular walking reduce risk for heart disease, it can be part of an exercise program to prevent colorectal cancer and support survivorship.
The National Heart, Lung, and Blood Institute suggests starting slow by walking for 30 minutes three days a week.
All adults should set a long-term goal to accumulate at least 30 minutes or more of moderate-intensity physical activity on most, and preferably all, days of the week. This regimen can be adapted to other forms of physical activity, but walking is particularly attractive because of its safety and accessibility.
They also point out that you can combine several short periods of exercise during the day.
