60+ minutes of exercise per day to maintain weight after age 50

[jobob]

Ever read the book Younger Next Year (or Younger Next Year for Women) ? Although the title is kind of off-putting (no, it's not about getting plastic surgery or looking like a kid again!), it has lots of very sound advice. The main message of this book is that people in their 50's and beyond really need to exercise 6 days a week for the rest of their lives, four days of which should be aerobic exercise. It's not about maintaining/losing weight, it's about maintaining muscle tone, balance, cognitive function and helping to slow down the inevitable biological decay that accompanies aging. Although the authors acknowledge that people who get off their butts and start exercising are apt to lose weight as well, especially if they also stop eating crap food.

I'm not going to delve into the hows & whys here. The book is available in some libraries, the Amazon site has a fairly lengthy preview of the book, and if you have a Kindle you could download a free sample. I recommend it, it's a good read IMHO.
