The American Heart Association and the American College of Sports Medicine have issued some new exercise guidelines and have clarified some of the old ones recently. Here's a quick summation of what they've mandated:

• Whereas the old guidelines recommended 30-minutes of moderate exercise most days of the week, they've clarified that we should be getting 30-minutes of moderate-intensity aerobic activity at least 5 days a week or 20-minutes of vigorous-intensity activity three times a week.
  
• This must be in addition to your day-to-day activities, so housework doesn't count. But it doesn't mean you need to fork out a bunch of money for a gym -- there are lots of ways to get in your daily activity.
  
• The new guidelines emphasize the important of weight-training too, particularly for seniors.
