Federal Government released its first-ever Physical Activity Guidelines for 2008 that provides scientific guidance to help people aged 6 and older improve their health through appropriate physical activity. Based on your age here are few quick to refer guidelines from the website :
Children and Adolescents (aged 6–17)
* 1 hour (60 minutes) or more of physical activity every day.
* At least 3 days per week. Muscle-strengthening and bone-strengthening activity on at least 3 days per week.
Adults (aged 18–64)
* 2 hours and 30 minutes a week of moderate-intensity, or 1 hour and 15 minutes (75 minutes) a week of vigorous-intensity aerobic physical activity,
* Muscle-strengthening activities that involve all major muscle groups performed on 2 or more days per week.
Older Adults (aged 65 and older)
* Follow the adult guidelines.
* Do exercises that maintain or improve balance if they are at risk of falling.
For all individuals, some activity is better than none. People without diagnosed chronic conditions (such as diabetes, heart disease, or osteoarthritis) and who do not have symptoms (e.g., chest pain or pressure, dizziness, or joint pain) do not need to consult with a health care provider about physical activity.
