We talk a lot about what we should do to age well: exercise, strength train, eat well, sleep, manage stress and stay active. But there’s another important piece of healthy aging that I don’t think we talk about enough. We need to measure how we’re doing.
Think back to when you were a child. Someone would ask, "What do you want to be when you grow up?" The answers were endless.
Have you ever wondered why one person seems to bounce back quickly after surgery or an illness, while someone else never quite recovers? Most people believe the answer is simply age or luck. But as an aging specialist, I've found that's rarely the whole story.
What if one of the most powerful ways to extend your lifespan isn't exercising harder, but exercising with other people? We've been led to believe that exercise helps us live longer simply because it strengthens our muscles, improves our heart health, and helps us maintain a healthy weight.
Recently we’ve been taught that inflammation is something bad, something we should eliminate as quickly as possible. But the truth is, your body actually needs inflammation to heal. In fact, inflammation is a lot like cholesterol.
What if the single most powerful predictor of how long, and how well you live isn’t genetics, your health, or even your diet, but rather your strength? We’ve been led to believe that longevity is mostly about managing disease, monitoring blood pressure, keeping cholesterol in check and taking the right medications. But I’ve found something very different. Many people believe that intense exercise means sweating buckets, lifting heavy weights, and pushing your body to its absolute limit. For many older adults, the word “intensity” can feel intimidating—even a little scary.
I hear it all the time from new clients walking through our doors at HouseFit. They’ll say things like, “I’m too old for intense exercise,” or “My body just can’t handle that anymore.”  Most people think aging is what causes their joints to ache, their energy to drop, and their recovery to slow down. But what if it’s not aging? What if it’s inflammation?
Researchers have started using the term “inflammaging” to describe the chronic, low-grade inflammation that develops as we get older  Most people believe that as long as they aren’t “couch potatoes,” they’re doing okay when it comes to physical activity. That a little walking here or some chores there are enough to keep us healthy as we age. But this is not true. In general people, especially older adults, are not moving enough to make a meaningful impact on their health.
 Staying active has always been good advice, but new research is showing that exercise does far more than strengthen your muscles or improve your balance. A major scientific review just confirmed something we see every day at HouseFit: Movement is one of the most powerful tools we have to slow aging at its deepest levels. Here’s what the science reveals.
