Your athletic performance is limited because your muscles overheat.

Not because you're weak or out of shape!

When you work out, your muscles burn energy and create internal heat.

As your muscles work, they create heat. As the heat rises, natural circuit-breakers within your muscles activate and your muscle activity begins to slow.  

You feel this process as fatigue and “burn.” Your body prioritizes muscle health over achieving that new personal best on the bike, treadmill or squat rack!

  • How to achieve muscle health and a new personal best?

  • You can cool your muscles from the inside to abate the rising temperatures and subsequent muscle fatigue.  By cooling your core, you’ll decrease muscle temperatures and optimize your performance!

How Our Core Cooling Technology Works


The CoolMitt® device chills water to the ideal cool-but-not-too-cold temperature and circulates it to a cooling pad where you have placed your hand.

The palms of your hand are like radiators that exchange heat through the patented CoolMitt® interface.


This process quickly cools your blood, sending it directly to your heart and from there out to your muscles.

Within seconds, you will begin to reduce your muscle temperature, and your performance will improve immediately.

Dramatically, your performance will improve.

When you strategically cool your blood between sets, or even use the CoolMitt® while exercising, you will see the benefits of Peak Performance through Muscle Temperature Control®.

The science of heat transfer.

As your muscles work, their internal temperature rises rapidly. To stop this dangerous rise in temperature, your muscles have natural fail-safe mechanisms that shut down the muscle’s activity.

The result? Fatigue.

Cooling your palms quickly sends cooling blood to your muscles via your heart - keeping the energy flowing to your muscles…boosting your endurance and capacity to become stronger, faster, and better.
