Testosterone: The Good, The Bad & The Ugly (For Dads Over 40).

Dads, is your testosterone really low—or have you just been running on empty for years?

You’re juggling work, family, and fitness (when you can squeeze it in). You’re constantly exhausted, struggling with belly fat, brain fog, and that feeling that you’ve lost your edge. And everywhere you look, you’re being told that low testosterone is to blame.

TRT (Testosterone Replacement Therapy) is being sold as the magic fix—but what if your hormones aren't actually broken? Is your health at risk?

What if your lifestyle is tanking your testosterone and you can reclaim your energy without relying on medication for life?

About the Podcast

The High Performance Gym
Performance without burnout
I’m Keir Wotherspoon.

I’ve been self-employed as a fitness coach and health educator for 16 years.
I ran a gym business for over five of those.
I’m also a dad of three.

Like many people, I’ve spent years trying to balance work, health, ambition, and family life, and I’ve learned how easy it is for energy to quickly disappear in the process.

This podcast is about understanding where that energy goes, and how to rebuild it without burning yourself out.

The High Performance Gym explores how your body, brain, and nervous system respond to stress, training, recovery, sleep, and pressure — and how small, repeatable changes can restore clarity, focus, and physical energy.

Some episodes are practical. Some are reflective. All are grounded in physiology, neuroscience, and real life.

If you want to perform well at work, show up at home, and still feel like yourself, this podcast is for you.

This is The High Performance Gym.
