PALA, or the Presidential Active Lifestyle Award, is a way for individuals and families to participate with thousands of others who are trying to be more active. The concept is simple: for 5 days a week, you are to engage in 30 minutes of exercise (for adults - youth is 60 minutes). You track and log your activity and progress and are awarded points for activity. The amount of points you earn allow you to qualify for different levels of the award.
It's a simple concept which has been used previously, but it's fun to see it gaining such support from the White House. My wife and I decided that we would sign our family up last night to encourage not only ourselves, but our children (specifically our 3-year old) to be more active.
P.S. If you want a fun personality to follow on social networks like Twitter and Instagram, @mytrainerbob, Bob Harper is great.
