Yes, walking is a great form of exercise for adults. It is a low-impact activity that is easy on the joints and can help reduce the risk of chronic diseases such as heart disease, stroke, and diabetes. Walking can also improve mood and cognitive function, and is a great way to get some fresh air and enjoy nature. The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic activity, such as brisk walking, per week for adults. So, get your comfortable shoes on and start walking!
