Is strength training the closest thing we have to a longevity prescription?

In this episode of Health Without the System, Dr. Tim Scott and Mia Scott break down the science behind muscle and why it may be one of the most powerful predictors of how well we age. From insulin resistance and brain health to bone density, hormones, and depression, muscle mass impacts nearly every system in the body.

They explain how lifting heavy supports metabolism, protects against dementia, strengthens bones, improves mental health, and helps preserve independence as we age. The conversation also dives into why muscle loss, known as sarcopenia, can accelerate disease, frailty, and early mortality.

If you want to improve your healthspan, not just your lifespan, this episode explains why strength training may be one of the most important investments you can make in your future.
