Bryan Johnson reports touching the rim at a 31-inch vertical

On 21 September 2026, Bryan Johnson posted that he touched the basketball rim with a 31-inch vertical jump and had five inches left to reach his dunk target. The post is a short performance update from the same multicomponent dunk-training project documented in earlier Blueprint records. It does not state how vertical height was measured, whether the jump was countermovement or standing, the number of attempts, footwear, warm-up, body mass, reach height, rim height, camera angle, assessor or raw trial data. “Five inches to go” depends on the unreported reach and target calculation, so it cannot be independently checked from the text alone. The result may indicate a change in jump performance, but a single public observation cannot identify which training, recovery, nutrition or sleep component caused it. It also provides no injury surveillance, comparator, prespecified endpoint or evidence about healthspan. This record therefore labels the post as an instrumented-looking but incompletely specified n=1 update. It does not turn Johnson’s progress into a general training prescription for older adults and does not support an evidence-grade change for creatine or any other ingredient.

Touched the rim at a 31-inch vertical; five inches remained by his stated calculation.
