Here’s Exactly How Exercise—Or Lack of It—Affects Aging Muscles. This Just Might Change Your Life

Buried deep inside your muscle tissue may be the secret answer to your flagging energy, growing waist size, and declining health. Take action now.

Under the glare of overhead lights, the paper-thin, ruby-red shavings of Rosangela Santiago’s muscle glow like fine gems. I can’t believe those just came out of my thigh, she thinks, watching as a scrubs-clad researcher places the five tiny slices into individual vials. Normally on a Tuesday morning, Santiago would be sitting at the office, processing invoices and getting a slow start to her day. But today she’s lying on a surgical table at the Translational Research Institute for Metabolism and Diabetes in Orlando, in the midst of a muscle biopsy and officially now a lab rat in the race for a more sophisticated understanding of why we get fatter, weaker, and sicker with age—and how it’s all intricately linked to the meaty fiber hidden beneath our skin.

A few moments from now, the research team will carefully preserve Santiago’s tissue in a liquid nitrogen tank chilled to minus 328 degrees, adding it to the thousands of other samples from people who, like Santiago, have volunteered for the TRI’s studies—studies that are contributing to a dramatic shift in how we think about muscle. For within those vibrant slivers of Santiago’s quadriceps lies precious information about her current health, as well as a forecast of what her future may hold. New science shows that it’s not just how much muscle you have that’s important—it’s what’s inside it that matters most. Metabolically active muscle—the kind that’s devoid of harmful fat and teeming with mitochondria, the metabolism-boosting powerhouses within cells—has a profound influence on everything from your weight to your energy levels to your risks of diabetes and heart disease. Even your chances of surviving a hospital stay or beating cancer are affected by the health of your muscle. This fitter, leaner, more-bang-for-your-buck tissue is so vital, in fact, that pharmaceutical companies are in hot pursuit of drugs that will enhance the metabolic capacity of muscle and help us maintain it as we age, as well as during hospital stays or times of illness.
