The VARYON Dumbbells are IO Fox’s first Foxite-based product, born from Varyolithography. Vulpine Dynamics announced them March 7–10, “promising to make fitness ‘a conversation between mind and matter,’” launched alongside the single “PWR UP PUP” (see The PWR UP Song Arc).

The Dumbbells “sell out their first production run.” Users “report increased motivation, mood elevation, and vivid dreams after intense sessions” — later understood as the first symptoms of Residual Field exposure. The wearable follow-up is the PWRBND.
