The workout drug [knowable magazine] Doctors are still learning about the benefits of exercise, and imagine prescribing specific exercises for particular conditions, the way they now prescribe medications and therapy.

As researchers tease out more of the details about how physical activity benefits health, the moment is fast approaching when exercise becomes not merely “a good thing to do,” but a medicine in its own right, just like pharmaceutical drugs. Several studies already point in this direction. For example, more than half of 64 adults with type 2 diabetes were able to stop taking medication to lower their blood sugar within a year of beginning a regular exercise program, [Bente Klarlund Pedersen, an exercise physiologist at the University of Copenhagen], and her team found. And a survey of more than 300 randomized controlled trials found that exercise was just as effective as drugs for people at risk of heart disease and diabetes, and was more effective than drugs for rehab after a stroke.

That very thing happened to me with Type 2 diabetes. I used to take medication to control it, but now I keep my blood sugar in check with diet and exercise. I think it took longer than a year to kick in, though.
