The Physical Activity Guidelines provide recommendations for how much physical activity individuals should engage in to maintain good health. For adults, it is generally advised to aim for at least 150 minutes of moderate-intensity aerobic activity each week, along with muscle-strengthening activities on two or more days. For children and adolescents, the guidelines suggest at least 60 minutes of physical activity daily, which should include a mix of aerobic, muscle-strengthening, and bone-strengthening exercises. Following these guidelines can help reduce the risk of chronic diseases and improve overall well-being.
