This post-apocalyptic home gym centers on a weathered leather punching bag pieced with canvas patches, copper rivets, and a heavy nylon strap, hung from industrial chains. Corrugated steel and raw concrete form a rugged shell, while neon magenta and cyan tubes cut through chalk dust. Charred timber and a rusted barrel fire underscore the salvaged look, shaping a high-impact training zone with tactile textures and cinematic grit.
