Exercise and physical fitness are crucial for maintaining a healthy lifestyle. Regular physical activity can help improve cardiovascular health, increase flexibility and strength, and decrease the risk of chronic diseases such as diabetes and obesity. It is recommended that adults engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities at least two days per week. Exercise can be enjoyable and varied, including activities such as walking, swimming, yoga, weightlifting, and team sports. It is important to consult with a healthcare provider before starting a new exercise regimen, especially if there are any pre-existing medical conditions.
