I'm trying to get my body back in shape again. A new study holds out the promise of longevity and even increased heath.
"Aerobic fitness alone is a key predictor of longevity," says Glenn Gaesser, an exercise physiologist at the University of Virginia. It doesn't matter whether the individual loses weight or if they have other risk factors associated with disease, Gaesser says.
Increasing fitness just a little bit, he says, "reduces the chances of dropping dead of a heart attack."
Church's study also found that the more exercise women did, the better off they were in terms of fitness. Women who biked or walked on treadmills for 3 hours per week ended up about twice as fit as those who exercised for just 71 minutes a week.
This study shows people don't have to exercise a lot to start seeing some benefits, says I-Min Lee, a professor of medicine at Brigham and Women's Hospital in Boston."
Now this does not mean that losing weight is of the menu. In fact if you want to go fast the best way to increase your speed is to lose weight.
