Burn with Kearns: Protect the Chassis While Keeping the Engine Running Week 3 – Kevin Kearns

by Coach Kearns, contributing writer, exercise and fitness

As we get older, many of us still want to train hard, stay athletic, and maintain the edge that makes us feel alive. The challenge is learning how to do that without destroying the body in the process.

At almost 60 years old, after decades working with fighters, athletes, executives, and everyday people trying to improve their health, I’ve realized something important:

Training for longevity is different than training for survival.

When we’re younger, we can often get away with excessive volume, poor recovery, lack of sleep, and pushing through pain. Eventually, though, the body starts asking different questions.

Can you recover?

Can your joints tolerate the workload?

Can your nervous system keep up with the stress?

Can you maintain energy, mobility, and strength year after year?

That’s where the idea of “protecting the chassis while keeping the engine running” comes in.

The body is incredibly adaptive, but it’s also cumulative. Years of stress, repetitive impact, inflammation, poor sleep, emotional stress, injuries, travel, and overtraining eventually leave a mark.

One of the most interesting areas of discussion in performance and longevity science right now centers around mitochondrial health.

Mitochondria are often referred to as the “power plants” of our cells because they help generate usable energy for the body. As we age, mitochondrial efficiency can decline due to factors such as chronic stress, sedentary behavior, inflammation, metabolic dysfunction, and aging itself.

This decline doesn’t just affect athletic performance. It can affect recovery, mental clarity, energy levels, endurance, and overall resilience. That’s one reason researchers have become increasingly interested in compounds like MOTS-c. MOTS-c is a mitochondrial-derived peptide currently being studied for its potential relationship to metabolism, exercise performance, insulin sensitivity, and healthy aging pathways. While research is still developing, early interest around MOTS-c largely centers on its possible role in helping the body adapt to stress and utilize energy more efficiently.

Personally, I became fascinated by mitochondrial support during one of the worst snowstorms Rhode Island has seen in decades.

At nearly 60 years old, I spent close to seven hours nonstop shoveling, carrying, clearing, and moving through heavy snow. What stood out to me wasn’t just the physical endurance — it was the recovery afterward and the ability to continue functioning at a high level despite the workload.

That experience made me look even deeper into the relationship between recovery, mitochondrial health, intelligent training, and performance longevity.

Not from a sales perspective. From an educational and coaching perspective.

Because for many people over 40 and 50, the goal is no longer to simply train harder.

The goal becomes:

moving well,

recovering intelligently,

maintaining strength,

protecting the joints,

supporting the nervous system,

and preserving quality of life.

Because longevity is not built through random punishment. It’s built through consistency.

The strongest people I know today are not necessarily the ones training the hardest every day.

They’re the ones still able to move, think, perform, teach, learn, and enjoy life decades later.

Protect the chassis. Keep the engine running.
