One of the easiest ways to maintain the shape of our body is to walk; it doesn't require any special equipment or a gym membership. The US Centre for Disease Control and Prevention says that adults should participate in at least 150 minutes of moderate-intensity aerobic activity per week for optimal health. This may be 30 minutes of walking per day for 5 days a week, or whatever works best for a person's schedule.
However, keep in mind that if done improperly, even this simple exercise may be less beneficial or even dangerous. These are some of the most frequent errors people make when walking, along with simple fixes.
