Best option under $1k... I definitely feel better at the end of my usual workout and I can squeeze a few more reps out where I couldn't before... It lives up to the hype.

How Cryo-1 helps
You’re Not Weak. You’re Overheating.
- Strength athletes don’t fail because their muscles are weak.
- They fail because their muscles overheat - usually before they realize it.
- That heat pulls the brakes on performance long before strength runs out.
Why You Fade in Later Sets
- Your body has a built‑in temperature control system designed to keep you comfortable.
- Every time you train, your muscles burn fuel to produce force. That process creates two unavoidable byproducts; Heat and Metabolic waste like lactate and hydrogen ions
- When this happens your muscles fatigue and each set gets harder to perform.
Palm Cooling Delays Fatigue
Studies show palm cooling can increase endurance by up to 25%. Over time this results in more reps, increased strength and faster recovery.
By using palm cooling for 1-3 mins between sets:
- Your body sheds heat and cools down
- Your muscles delay fatigue
Pro athletes in the NBA, NHL, MMA and NFL use palm cooling to boost performance and you can too.
