If your driver’s license says 50, but your body functions like a 35-year-old’s—what age are you, really? 

You know your chronological age: the number of years you’ve been on the planet. Your biological age is a better indicator of how old your body really is. 

Everyone ages at the same rate chronologically—but biologically? That’s another story. 

Poor diet, stress, inactivity and a whole host of other factors all age you faster than you realise. Often leading to your biological age being much higher than your chronological age. 

The good news is that a new era is upon us…modern science has unlocked the secrets of longevity. Ageing backwards is no longer the stuff of fairy tales. 

 

How To Determine Your Biological Age? 

There are several ways to determine your biological age: 

• Epigenetic clocks (e.g., Horvath clock, GrimAge): DNA methylation patterns. 
• Telomere length: shorter telomeres = older biological age. 
• Biomarker panels: inflammation (CRP, IL-6), glucose regulation, lipid profiles. 
• AI-based facial recognition + movement patterns (emerging tech). 
• Functional age tests: VO2 max, grip strength, muscle mass, reaction time. 

Of course, we can’t reverse your chronological age, but your biological age is much more malleable. 

Factors such as: 

• Exercise (especially resistance + cardio) slows cellular aging. 
• Nutrition: fasting, antioxidants, anti-inflammatory diets. 
• Sleep & stress management: cortisol’s impact on aging. 
• Alcohol/smoking/environmental toxins: how they accelerate biological wear. 

All have a huge effect on your biological age and all of them are 100% under your control. 

 

Why Is This important? 

Biological age correlates more strongly with risk of heart disease, cancer, Alzheimer’s, etc. 

 

​​​Is It Possible? 

Biohackers like Brian Johnson would argue yes and his latest documentary on Netflix tells his tale of how he’s reversed his age by over 20 years. 

​​​The TRIIM trial*, where researchers used a combination of growth hormone, metformin, and DHEA to shave an average of 2.5 years off participants’ biological age in just 12 months, based on epigenetic markers. 

Lifestyle changes—like adopting a whole-foods diet, managing stress, getting quality sleep, and regularly engaging in both resistance and aerobic training—have also been shown to improve markers of biological youth. 

 

How We Measure Your Biological Age 

As part of our 6 week ‘Stealing Fire’ programme, we run you through a comprehensive series of functional tests to determine your biological age. 

These tests are totally non-invasive and can be done in a gym quite easily. 

Testing like this enables us to see how your body is performing across a range of different areas, and includes areas as diverse as reaction time, mobility and balance but also includes how well your internal systems are performing. 

We can then use this to shape a bespoke plan specifically targeted at those areas you need all with the aim of reducing your biological age in as short a time as possible. We retest you at the end of the program so you can see just how effective our methods are. 

You can’t stop time—but you can slow the biological clock.
