Here’s something wild…

Your grandad probably had higher testosterone than you… even if he never touched a barbell. In fact, a 25 year-old today, has the same levels of T as a 50 year-old in the 1980's.

And no, it’s not just because we’re getting older. Even young men today have less testosterone than young men did 30–40 years ago. Lab-tested, peer-reviewed, global data confirms it.

For gym owners and gym-goers alike, this matters. A lot.

​

📉 The Testosterone Drop Is Real

Studies from the U.S., Finland, and Europe all say the same thing:

Men’s average testosterone has dropped about 1% per year for the past few decades.

​

A 65-year-old in 2002 had 15% less T than a 65-year-old in 1987

​

Even fit, lean men are affected - it’s not just about body fat

​

And while we don’t have identical UK data, experts agree: British men are seeing the same trend.


🔍 What’s Causing the Decline?

It’s not just one thing. It’s a storm of modern life:

​

Rising obesity and sedentary lifestyles. We've handed most of our manual labour to machinery.

​

Endocrine-disrupting chemicals in plastics, food packaging, and cleaning products

​

Chronic stress and poor sleep

​

A drop in smoking (which slightly boosts T - not worth the trade-off, obviously)

​

Even grip strength in men has dropped since the 1980s… just let that sink in.

​

🏋️‍♂️ Why It Matters in the Gym

Testosterone (as I’m sure you know) is key for:

​

- Muscle growth & strength

​

- Fat loss

​

- Recovery & energy

​

- Motivation & mental sharpness

​

​

If your clients (or you) are training hard but not seeing results, low T might be part of the problem, even if it’s still within “normal” range.

​

💪 How to Fight Back

The gym is still one of the best weapons against this decline.

​

Encourage or focus on:

​

Heavy compound lifts

​

HIIT & sprinting

​

7–9 hours of sleep

​

Sunlight or Vitamin D

​

Low-plastic, whole-food nutrition

​

Stress management tools (cold exposure, breathwork, etc.)

​

You can’t change the environment you were born into, but you can train your way through it.

​

🤔 Final Thought

Gym owners - you’re not just helping people “get fit.”

You’re helping modern men overcome a hormonal disadvantage they didn’t even know they had.

​

Testosterone is dropping. The mission’s bigger now.

Train smarter. Coach harder. And help your members thrive in spite of the modern world.
