Test 01
Y-Balance Test, Lower Quarter
Reach distance in three directions, each leg, expressed as a percentage of your own limb length. Control, not flexibility.
Pillar 03 of 04
Stability
Strength fails gradually. Stability fails in a single moment. This pillar measures the system that keeps you upright.
A balance target with three reach directions. As you scroll, the reach arms extend and a swaying centre point steadies, while the asymmetry readout narrows.
Three directions of reach. Both legs.
Measured against your own limb length.
The gap between sides is the tell.

Why it matters
The pillar that fails suddenly
Stability is not one quality. It is the integrated output of balance, joint control, mobility and strength: the nervous system holding the body's position when life pushes on it.
Falls are the leading cause of injury death after 65, and the risk is set decades earlier. We test it before life tests it for you.
Falls are the leading cause of injury death after 65
Which is why we test it in your 40s, not your 70s

Test 02
Asymmetry Watch
Left measured against right. The difference between sides often matters more than the total.
Scored against age-and-sex norms

How we train it
The prescription
- ASingle-leg strength in every programme, both sides counted
- BMobility trained with load and control, not stretching alone
- CBalance challenged on purpose, while it is still cheap to train
The score
Equal weight, by design. No pillar can carry another. Four scores combine into one Healthspan Score out of 10.
