Very few Americans exercise in any significant way. The President's Council on Physical Fitness and Sports estimates that only one in five Americans exercises for the healthy minimum of 20 minutes, three or more days a week. In fact, the average American gets less than 50 minutes of exercise per week. Even worse, two out of five Americans are completely sedentary. But there is hope.
Fit people are also eight times less likely to die from heart disease.
Once you have made the decision to go forward and accept change, the hard part is over. Sure, there is plenty of work to be done, but it really doesn't matter how long this new process takes. If you allow changes to take place over several years, your body will adjust comfortably, and you will be more likely to maintain the healthy lifestyle permanently.
