If you've been sedentary for a while, you should start with brisk walking. Walking is the perfect aerobic activity. You don't have to possess any particular skills or talents for it, while it gives you satisfactory aerobic benefits. Walking has a relatively easy impact on joints as one foot always touches the ground. Also, you don't need any special equipment except a good pair of shoes; and you can enjoy walking anytime and anywhere.

There are very few reasons not to walk – such as bad weather and darkness, or lack of safe paths or sidewalks.

Walking helps you strengthen leg and lower back muscles. If you swing your arms, do pole walking, or carry light hand weights you keep your upper body muscles trained as well.
