Fitness age: the age of your physical fitness
Your ID says one thing, your body another. Fitness age shows how "young" your body works: it's determined by cardio endurance, strength, neuromotor function, body composition and lifestyle. The calculator combines them into a single age and shows which factor pulls it up and which pulls it down.
How fitness age is calculated
Each of the six factors is compared with what's typical for your sex and age and converted into a "contribution in years": strengths make your fitness younger, weaknesses make it older. The sum of the contributions gives your fitness age; together with your metabolic biological age it forms the final age of your fitness.

Fitness age calculator
Sex, age, height, weight and waist are required. The other fields are optional, but the more you fill in, the more accurate the result. Take measurements under the same conditions, ideally in the morning on an empty stomach.

What makes up your fitness age
Different body systems age at different rates. Fitness age brings together six areas — each with its own contribution, and almost every one can be "rejuvenated" through training and lifestyle. If you want to assess only the aerobic engine in more depth, see fitness age from VO₂max.
How to measure yourself correctly
The accuracy of the result depends on technique. Take measurements under the same conditions — that way you can compare the trend between calculations fairly.
How to make your fitness younger
The fastest lever is regular aerobic exercise, but a lasting effect comes from combining cardio, strength and recovery. Introduce one or two changes at a time, and track progress at the cellular level through biological age from blood tests.
