Welcome back to Get Fit Guy. I'm Kevin Dunn. This week I'm going to look at aging and how the best thing we can do for ourselves to maintain our physical capacity is to move. You've got to use it or lose it.

I've talked before about the idea of fitness or physical training as a form of medical

intervention to hedge against the relentless march towards entropy. So perhaps I might be repeating

myself here, but since we all need to hear something a few times before it sinks in,

that's fine. This might also be the first time some people are listening in,

and that's great. Welcome to the Get Fit Guy family. We all age, but there's an idea about

sick aging. That is that instead of being able to remain fit, healthy, and free of disease as we grow

older, we experience a host of age-related sicknesses.

These include but are not limited to decreased muscle mass, exercise or anabolic resistance,

insulin resistance, hyperglycemia, hypertension, increased serum lipids and increased visceral

fat. These metabolic syndromes combine to manifest as early frailty,

type 2 diabetes, and then the resulting polypharmacy, reliance on multiple medications,

and the unwanted side effects of those include more muscle mass loss, fatigue, brain fog, and so on.

Over time, these processes of aging and polypharmacy become more and more interconnected.

One way out of the repeating loop is exercise as an intervention.

We can increase our muscle mass, decrease our insulin resistance, blood pressure and body fat,

all with a smart and recoverable training protocol.

So where do we start?

So I've been trained for like at least 12 years now that you have to start with strength training.

That's the fundamental prescription for an aging adult.

This is because the first things we lose, muscle mass and bone mineral density,

are addressed most effectively by strength training.
