PERFORMANCE

What the work changed.

The most interesting numbers are not just how much training I recorded. They are the changes that happened alongside it: body weight, aerobic fitness, resting heart rate, recovery markers and endurance capacity.

Body reduction −58.1%

186 kg → 78 kg.

VO₂ max gain +~84%

29.37 → 53.96.

Resting heart rate trend ~74 → ~46

Early versus recent recorded averages, in bpm.

THE ENGINE

Less body weight was only one part of the transformation.

Current VO₂ max 53.96
Recent HRV trend ~48 ms
2026 running 899 km
Recorded cycling 4,631 km
THE WORK BEHIND IT

The performance numbers came from repeated volume.

Training Recorded volume What it represents
Running 238 runs · 1,422 km One of my main endurance disciplines; repeated 10 km runs became normal training
Cycling 725 workouts · 4,631 km A major part of the endurance journey and my highest recorded workout count by sport
Hiking 33 hikes · ~104 km Outdoor distance, terrain and sustained effort — the third core endurance discipline
Strength 173 recorded sessions · ~121 h A minimum, not my total strength history; many gym sessions were never logged
All recorded workouts 1,363 workouts · 1,104 GPS routes The broader Apple Health record behind this snapshot, including activity beyond the core disciplines
HOW TO READ THE DATA

Strong evidence of the journey, not a perfect diary of every session.

Data window 2021 → 2026

The overall recorded journey begins 9 February 2021 and this snapshot stops at 20 September 2026 — about 5 years, 7 months. Later activity is not included until the site is updated.

Strength recording RECORDED MINIMUM

I often trained without starting a workout on my Apple Watch, either because I forgot or simply did not care about logging every gym session. The real strength volume is higher than the recorded number.

Walking NOT A TRAINING PRIORITY

Apple Health contains walking activity, but walking was never one of my serious training disciplines. I put my endurance time into running, cycling and hiking instead.

Apple Health scope RECORDED, NOT COMPLETE

The numbers show what Apple Health and Apple Watch captured. They are useful for trends and milestones, but they should not be read as a complete log of everything I did.
