Hook
Born from the ooze and fueled by bulks gone wild — the Mutant Slice Beast is the cheat meal that fights back. A dripping, jacked pizza fiend with veiny forearms and a mean grin. Front print: the monster pie mid-rampage. Back print: retro sewer-hero style The Shape Fitness wordmark — because this cult runs on protein and PRs.
Why it hits
- Horror × Hypertrophy: 80s cult vibes with a mass-monster twist.
- Gym-ready DTG: High-contrast artwork that pops under gym lights.
- Everyday fit: Built for training days or late-night slice runs.
- Back graphic: “The Shape Fitness” in retro mutant-sewer style.
The Iron Demon (brand lore)
Iron Demon is “The Shape” that lives between reps. That switch that flips when the weight bites back — the half-man/half-iron alter-ego that surfaces with glowing eyes when it’s time to move real weight and you refuse to rack it. It’s the shadow in the corner of the gym. Watching, waiting, that red-eyed focus you feel right before the rep that matters. Wear it as a reminder: let the demon out when it counts. No excuses. No Mercy. Just reps.
