What is behind the BioAge?

The EGYM BioAge acts as a bridge between active physical training and long-term health benefits. It is engineered to give commercial operators a powerful commercial advantage by turning abstract workout data into a clear, visual success metric.

To determine this score, the EGYM Ecosystem utilises a sophisticated analysis of various scientifically proven factors directly related to physical performance and biological resilience. It relies strictly on physiological data and fitness data collected seamlessly across the training floor.

Note: The EGYM BioAge is exclusively a fitness guidance tool and healthspan indicator, not a medical diagnostic tool. Under no circumstances should its outputs be framed as medical data.

The four pillars of BioAge

The four pillars of the BioAge metric function as specialised performance categories. The parameters inside each category ensure the highest degree of real-world precision:

• Strength: Full-body power-to-weight ratio, benchmarked against millions of workouts
• Metabolism: Includes skeletal muscle mass (SMM%) and body fat percentage as primary metrics, alongside waist-to-hip ratio.
• Cardio: Includes VO2max and blood pressure, which acts as a risk guard only.

• Flexibility: Functional range of motion, capped at a maximum deviation of ±20 years from chronological age

   

How is the BioAge score calculated?

The BioAge provides a highly precise, scientific assessment of how well the body is ageing by comparing a member's performance against actual, authenticated peer data.

The underlying mechanics

Cardio, Metabolism, and Flexibility: In these categories, a member's score is compared strictly to the average performance data of their exact chronological age group. To keep assessments grounded and realistic, individual category scores feature a maximum deviation cap of ±20 years from the member's true chronological age. Strength: The strength baseline is calculated using a massive dataset containing millions of real-world EGYM workouts. Rather than relying on abstract laboratory projections, members are evaluated against the realistic human capabilities demonstrated daily across our global network.

How do the BioAge parameters relate to healthspan?

Every metric tracked inside the EGYM ecosystem corresponds to validated principles of sports science and preventative health.

Strength BioAge

The Strength score evaluates full-body force generation and the user's power-to-weight ratio. Utilising the massive global dataset of real-world EGYM workouts, this metric establishes a precise baseline for long-term physical capability, functional independence, and sarcopenia prevention.

Metabolic BioAge

The Metabolism score focuses heavily on tissue composition and overall metabolic efficiency.

• Skeletal muscle mass (SMM%) and body fat percentage serve as the primary metrics in this category, reflecting modern sports science's emphasis on preserving active lean mass to maintain high metabolic rate and insulin sensitivity.
• Waist-to-hip ratio is included to monitor abdominal fat distribution, which correlates strongly with cardiovascular resilience.

• Body Mass Index (BMI) serves purely as a fallback metric. If precise body composition data from a connected smart scale is missing, BMI is used as a backup, but it will not override or alter the score if exact fat and muscle percentages are available.

   

Cardio BioAge

The Cardio score assesses the efficiency of the cardiorespiratory system.

• VO2max is tracked as the gold standard indicator of cardiovascular fitness, aerobic capacity, and all-cause mortality risk reduction.
• Blood pressure plays a highly specific role as a guard against health risks. Because normal blood pressure is a baseline expectation for stable health, regular readings will not artificially lower a member's biological age. Instead, blood pressure only impacts the BioAge if it is clinically elevated, adding up to 20 years to the category score to accurately reflect the associated health risk.

• Resting heart rate has been completely removed from the calculation to eliminate day-to-day fluctuations caused by temporary lifestyle variables like poor sleep or acute stress.

   

Flexibility BioAge

The Flexibility score evaluates a user's functional range of motion, collected via automated tracking on the EGYM Fitness Hub or Smart Flex equipment.

Maintaining joint mobility and muscle length is essential for pain-free daily movement and injury prevention. Like the other physiological categories, this score is capped at a maximum deviation of ±20 years from the user's chronological age to ensure consistency and reliable data modelling across the entire assessment.
