Exercise Helps Ward Off Disease

Exercise Helps Ward Off Disease

Research has shown that exercise can slow or help prevent heart disease, stroke, high blood pressure, high cholesterol, type 2 diabetes, arthritis, osteoporosis (bone loss), and loss of muscle mass, says Astorino.

It also helps ease some aspects of the aging process.

"Because exercise strengthens the muscles and joints, it is going to reduce your odds of having some of those aches and pains and problems most adults have, mostly because of the inactive lives they lead," Bryant says.

Provided you don't overdo it, he says, exercise can even boost immune function -- so you spend less time down with a cold or flu.

"There isn't a major health problem where exercise cannot have a positive effect," says Byrant.
