There are no definitive rules on how to increase your level of physical activity, but you can start by looking at your attitude toward exercise. Optimism is the most common personality trait. This characteristic is linked to the ability to reduce stress. Optimists tend to live healthier lifestyles that include regular physical activity, eating a healthy diet, and not smoking or drinking excessively. If your attitude is positive, you are likely to exercise more regularly than those who are pessimistic.
