The Challenge Is Over... But the Giveaway Runs Longer!
*Full honesty: the suit isn't completely finished. It's wearable but not painted. I ran out of time, and the paint job deserves proper dedication, not a rush. It still did its most important job though: it got me fit.

CHAPTER ZERO
Before / After
On January 17, 2026 I weighed 200 lbs (91 kg), didn't have an Iron Man suit, and announced a 4-month challenge to fix both. I'd tried to lose weight for twenty years, and somehow, an uncomfortable plastic suit is what finally got me there.
The suit still needs its paint job. The body came out fine.
