GRFP “The Devils” Flow Muscle Tank — 6×6×6 Edition
Six exercises.
Six rounds.
Six reps.
If you know, you know.
The GRFP “The Devils” Flow Muscle Tank honors one of our most infamous Theme Day workouts — the 6×6×6 grind that tests strength, grit, and sheer willpower. This tank pairs a soft, drapey silhouette with bold GRFP graphics, dropped armholes, and a relaxed feminine fit that keeps you moving freely through every rep (or recovering from them).
Lightweight, breathable, and flattering on every body, it’s built for training, layering, or simply repping that you’ve survived The Devils — or you’re about to.
