On today’s episode, we’re diving into the Nice Rocc, a $975 handheld palm-cooling device designed to accelerate muscle recovery and boost performance. Using electronic cooling based on the Peltier effect, the Rocc reaches its target temperature of “50 to 60 degrees Fahrenheit” in about two minutes. By holding it for at least two minutes, you send cooled blood through your body to drop core temperature fast.

Weighing 5.3 pounds, the Rocc is iceless—no ice packs or setup required—just charge it for two hours of runtime. Athletes can use it between sets, during games, or even before sleep to ease into a parasympathetic state. In my own testing, I squeezed out extra reps on AMRAP push-ups and felt noticeably fresher between deadlifts. As the review notes, it “forces you to focus on your recovery instead of just sitting and zoning out.” Though pricey, “this thing is worth it” for serious athletes seeking every edge.
