          For children 5-11 years:<\/u><\/p>\n

          \n
          • For health benefits, children aged 5-11 years old should accumulate at least 60 \u00a0minutes of moderate to vigorous intensity physical activity daily. This should \u00a0include: \u00a0o Vigorous-intensity activities at least 3 days per week \u00a0o Activities that strengthen muscles and bone at least 3 days per week \u00a0o More daily physical activity provides greater health benefits \u00a0For youth 12-17 years:<\/u><\/li>\n
          • For health benefits, youth ages 12-17 years should accumulate at least 60 minutes of \u00a0moderate to vigorous intensity physical activity daily. This should include: \u00a0o Vigorous- intensity activities at least 3 days per week \u00a0o Activities that strengthen muscles and bone at least 3 days per week \u00a0o More daily physical activity provides greater health benefits<\/li>\n<\/ul>\n

            \n
            • \u00a0\u00a0 To achieve health benefits, adult\u2019s ages 18-64 years should accumulate at least 150 \u00a0minutes of moderate to vigorous intensity aerobic physical activity per week, in \u00a0bouts of 10 minutes or more. It is also beneficial to add muscle and bone \u00a0strengthening activities using major muscle groups at least 2 days per week. More \u00a0physical activity provides greater health benefits<\/li>\n<\/ul>\n

              For older adults 65 years and older:<\/u><\/p>\n

              \n
              • \u00a0\u00a0 To achieve health benefits, adults ages 65 years and older should accumulate at least \u00a0150 minutes of moderate to vigorous intensity aerobic physical activity per week, in \u00a0bouts of 10 minutes or more. It is also beneficial to add muscle and bone \u00a0strengthening activities using major muscle groups at least 2 days per week. Those \u00a0with poor mobility should perform physical activities to enhance balance and \u00a0prevent falling. More physical activity provides greater health benefits<\/li>\n<\/ul>\n
