How to Keep Muscles Strong as You Age

Almost everyone shrinks with old age. Many older adults have more difficulty gaining muscle than they did in their childhood and teenage years. And when it comes to maintaining that muscle, the phrase “use it or lose it” holds weight, says Michelle Gray, a physiologist and professor of exercise at the University of Arkansas.

“I work primarily with older adults who are trying to either build and/or maintain muscle throughout their life span, and really how that happens is you use it or lose it,” Gray says.

But she adds that not all hope is lost. “It really is the neurology, as well as the muscular system and the interactions between the two, that changes,” she says. “There’s a fair amount of evidence that says all of those things are still there and [that] we can retrain them.”

Several factors contribute to involuntary age-related muscle loss. The exact age people start to see muscle mass decline varies, Gray says, but many begin to see noticeable changes in their 30s. Studies suggest that muscle mass decreases by about 3 to 8 percent per decade after age 30 and at higher rates after age 60. Losing that strength may not only be frustrating in keeping up with daily activities but can also have significant health consequences.
