Walking is the simplest yet is the most underrated form of exercise. Walking can be a good workout depending on how long and often you walk, and may be a better choice for some people. It has both physical and mental benefits, such as improvements in blood pressure, reduces risk of heart disease and stroke in both men and women, strengthens memory, and lifts your spirit. Walking for 30 minutes a day on most days of the week is a great way to improve your overall health and is recommended by physicians. If you can’t manage 30 minutes, remember: even a little is good, but more is better.
