What Is the Best Type of Exercise?

Any exercise you can do on a regular basis is the best kind of physical activity. Walking is considered one of the optimal choices because it’s easy, safe, and inexpensive. It also doesn’t require training or special equipment, except for a pair of good walking shoes. Brisk walking can burn as many calories as running and is less likely to cause injuries than running or jogging. Additionally, walking is an aerobic and weight-bearing exercise, so it is great for your heart and helps prevent the weakening of the bones known as osteoporosis.
