The bulk, measured.

I built JSON.fit. Now it's bulking me from 77 to 90 kg. Every scan, photo and number lands here as it happens, whether it's working or not.

The trend

One line to watch.

Bodyweight against the 90 kg target. The dots fill in scan by scan.

The detail

Everything else, if you want it.

The complete scan history and the decade before it, out of the way until you ask.

Scan history · every metric, every month

// same Evolt 360 every scan · Δ is total change from baseline · a column is added each month · "-" means not measured

Before the tracker · how I got to the start line

185 cm and under 60 kg right through my teens. 67 kg leaving uni. A first bulk got me to 82 kg in 18 months, but I did it the miserable way, the same meals every day, forced down, so it never stuck and I drifted back to 77 kg. That's why JSON.fit exists, and why this run is built to last. Same size I've already proven I can reach, done properly this time.

Everything on the page above is measured on the same Evolt 360 machine, every month, and nothing gets published unless it was measured. These two old phone photos are the one deliberate exception, included for context. The tracked, honest record starts at 77 kg on 1 July 2026.

Same app. Your numbers.

The program, the meal plan and the tracking on this page all come out of JSON.fit. Same free app, same tools.
