Train Harder. Recover Faster. Get Stronger.

In controlled strength trials, athletes using palm cooling increased total training volume by up to 144% compared to controls.

Watch How It Works

Boost Your Performance

Elite performance isn’t about pushing harder - it’s about managing heat. What if you could get WAY more out of your workout with zero extra effort? It may sound like internet hype, but the science is real. In controlled Stanford studies subjects achieved:

  • Up to 144% more training volume 
  • 20–40% longer endurance 
  • Nearly 2× more total reps before exhaustion

Performance gains occurred without additional training, stimulants, or recovery time - simply by managing heat between efforts.

the problem

Heat Is a Performance Killer

Every athlete hits a familiar wall: your muscles still feel capable, but output drops, reps slow, and endurance fades sooner than it should.

That wall isn’t willpower — it’s heat.

As you train, your muscles generate heat and metabolic byproducts like lactate and hydrogen ions. As core temperature rises:

  • Muscle contraction efficiency drops
  • Enzymes responsible for energy production slow
  • Fatigue accelerates even when strength remains

The hotter your body runs, the faster performance declines.

The SCience

Why Palm Cooling Works

Our palms are one of the body’s fastest heat‑exchange zones.

Specialized blood vessels called arteriovenous anastomoses (AVAs) allow heat to move rapidly from circulating blood to the outside world.

Stanford‑led thermoregulation research discovered that:

  • Cooling the palms pulls heat directly from the bloodstream
  • Muscle efficiency is preserved longer under load

The result: delayed fatigue and dramatically increased work capacity.

In controlled trials, subjects performed nearly twice as many total reps before exhaustion. Additional studies showed 20–40% improvements in endurance in hot conditions, allowing athletes to sustain effort significantly longer before fatigue set in.
