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.
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.
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.
Cryo‑1
Cryo‑1 brings this laboratory‑proven science into a portable, everyday performance tool.
Unlike ice baths or bulky recovery gear, Cryo‑1:
- Targets the palms at the optimal cooling range
- Works in 60–90 seconds between sets
- Is compact, rechargeable, and gym‑ready
- Requires no prep, water, or downtime
How do I get maximum performance from the Cryo-1 Device?
For best results, we suggest turning Cryo-1 on a couple of minutes before you need it. We recommend setting it to maximum power - three cool lights for cooling or three warm lights for warming- and allowing it to run on its own for 1–3 minutes. This lets the device reach its optimal temperature faster than if it’s being held immediately.
That’s not to say you won’t feel relief right away when using it handheld, but pre-running ensures the coldest or warmest effect.
Each cycle runs for about 20 minutes, giving you plenty of time to enjoy a session and then turn it off before the cycle completes.
How do I use Cryo-1 for workouts?
Hold Cryo-1 in your palm for 1–3 minutes between sets or intervals.
You should feel an immediate sense of coolness throughout your body, but the real benefit comes in your next effort -whether that’s a heavier lift, a sharper sprint, or a steadier performance.
This brief cooling lowers core temperature and helps reverse the buildup of heat and acidic byproducts in working muscles, restoring enzyme efficiency and contraction strength so you can perform stronger on the very next set.
Think of it like letting an engine cool down so it runs smoother and with more power on the next lap.
How is it different from an ice pack?
Ice is too cold to effectively cool the body
without causing blood vessels to constrict. This slows circulation and
limits heat transfer.
Cryo-1, on the other hand, applies
controlled “cool‑not‑cold” cooling that keeps blood flowing, removing
heat faster and more effectively.
How long does Cryo-1 take to work?
Most users feel results within 60–90 seconds.
How long does the cooling effect last?
A short session with Cryo-1 can deliver benefits that last well beyond the moment of use.
For athletes, cooling the palms between sets or sprints can sharpen the very next effort and sustain performance for several minutes to several hours.
For women using Cryo-1 to stop hot flashes, a single session often ends the episode entirely and provides comfort until the next occurrence.
In this way, the relief from one use can carry through workouts, daily activities, or extended periods of calm, making each session remarkably effective.














Cryo-1 is a palm cooling and warming device designed to boost physical performance and support heat recovery.
Cryo-1 is designed to help athletes perform, train and recover more effectively; provide rapid comfort for women during hot flashes; and anyone recover faster from heat stress (including kids playing sport).
Cryo-1 is compact, rechargeable, and easy to use.
