When it comes to health and fitness, your chronological age tells only part of the story. Two people of the same age can have very different levels of strength, fitness, and overall health. This is where biometric age testing becomes valuable.
As part of the TFH LIFE program, we use a comprehensive testing system called LifeAge. LifeAge is a biometric age score based on how your body is currently functioning across key areas of health and performance. Rather than guessing where you’re starting, LifeAge gives a clear, measurable picture of your current fitness and provides a benchmark to improve upon.
What Is LifeAge?
LifeAge is calculated using a series of proven tests that assess body composition, cardiovascular fitness, strength, and health markers. Each test provides insight into how efficiently your body is working compared to age-related norms. When combined, they create a single, easy-to-understand score that reflects your biological age rather than the number on your birth certificate.
The Tests Behind LifeAge
Body Composition (BMI & Body Fat Percentage)
BMI and body fat percentage help assess how your body is carrying weight and how much of it is metabolically active tissue. Higher levels of body fat are associated with reduced performance and increased health risk, while improvements here often lead to better energy levels, movement, and overall wellbeing.
Blood Pressure
Blood pressure is a key indicator of cardiovascular health. Monitoring it allows us to understand how well your heart and circulatory system are coping with daily demands and training stress.
Grip Strength Test
Grip strength is one of the strongest predictors of overall strength and long-term health. It reflects neuromuscular function and has been shown to correlate closely with ageing and functional capacity.
Cardiovascular Fitness (Bike Erg Ramp Test)
The ramp test on the Bike Erg assesses how efficiently your heart and lungs respond to increasing effort. Cardiovascular fitness is one of the most important factors in reducing biological age and improving long-term health outcomes.
The Benefits of Biometric Age Testing
Clarity
LifeAge removes guesswork. You know exactly where you stand and which areas need the most attention.
Personalisation
Training is tailored to your results, ensuring the program meets your current ability rather than a one-size-fits-all approach.
Motivation
Seeing your LifeAge improve is a powerful motivator. Progress becomes measurable, not just something you “feel.”
Accountability
Retesting allows you to track real change over time, keeping training focused and purposeful.
Long-Term Focus
Rather than short-term weight loss or performance goals alone, LifeAge encourages improvements that support longevity, resilience, and sustainable health.
LifeAge and TFH LIFE
TFH LIFE isn’t about training harder for the sake of it. It’s about training smarter, with clear data guiding every decision. LifeAge gives you a starting point, a direction, and a measurable outcome, helping you reduce your biological age while building strength, fitness, and confidence over time.
