Over the years, many people have asked me if there is such a thing as being too old to exercise. My standard reply is an automatic "No!" "But isn't it dangerous for older people to be lifting weights?" Again, I respond with a resounding "No, it's not dangerous! It's actually the best thing for them." People from every generation can benefit from exercise; in fact, mature people have the most to gain from it. Studies have shown that regular strength training can increase muscle mass by more than one pound per month in the older population. On top of that, resting metabolism has been shown to increase by more than two percent per month. This is a good equation because it realistically reverses some of the degenerative processes that can happen with aging.
