“Straight from the community — the accountability is what made it stick for me.”

— Markus, Challenge 20.0 Winner

Markus logged this journey across 5 challenges, with personalised programming, nutrition tracking and regular check-ins throughout.

Individual results vary — this is one participant’s documented result, not a promise of your own, and it required consistent training and nutrition. Weight loss of around 1–2lb per week is the generally accepted safe rate; where a result was achieved faster it should not be taken as typical or as a target. Always consult your doctor before starting a weight-loss programme.

Tracked in the 8WTC app for 350 days

Markus’s year on the system — five challenges, back to back.

This is the long game: a cut, a cut, a reverse diet to bring calories back up, a muscle-building block, then a cut — 308 days logged at 99.8%. The net number undersells it: Markus lost 23.7kg across the cuts and put weight on in the middle phases on purpose.
