The new “Physical Activity Guidelines for Americans” has been released. The guidelines have been updated since the 2008 edition. The adult basic activity requirements is still at least 150 minutes of moderate activity or 75 minutes of vigorous activity per week plus two days of weight-bearing strength training. A very important change is preschoolers (3-5) should be active about 3 hours per day. And kids (6-17) should be active for 60 minutes per day. Movement is exercise. And exercise is medicine.
