Volume 48 | Palmar Cooling
Sports performance trends of 2025 including palmar cooling, new Equinox rucking program, and Giannis invests in superhuman longevity app.


Palmar Cooling | The New Sports Performance Hack
Ice baths and cryo chambers are great but I’m all-in on palmar cooling being the hottest (or should we say coolest?) performance trends over the next decade.
Palmar cooling—rapidly cooling the palms to supercharge endurance, strength, and recovery. Here are the industry leading brands.
Kühler | Effortless Cooling on Demand
Patented palm-cooling device based on Stanford research. No ice, no water, no tubes—just rapid fatigue reduction and performance gains anytime, anywhere.
These are like small video game controllers. I interviewed founder Braden Ostepchuk late last year and love what he is building. I think the size, design, and powerful function will be a game-changer here.
CoolMitt | VasoCooling Breakthrough
Developed by scientists to delay fatigue, speed recovery, and elevate performance. Trusted by pro athletes across MLB, NFL, NBA, NHL, and global soccer.
These are the big blue gloves you’ve probably seen appear the most whether on the Huberman Lab podcast or one of Novak Djokovic’s Tennis matches.
Apex Cool Labs | Narwhals Next Gen Cooling
Portable “cool-not-cold” palm cooling tech designed for long-lasting recovery, strength maintenance, and heat stress relief. Lighter, tougher, and engineered for serious athletes.
These things look like some sort of kitchen appliance. I like the portability and excited to watch them grow. I have not tried this product yet!
You always see Hyperice Venom or Hyperice X on the sideline of NBA and NFL athletes during games. Palmar cooling devices are the next wave.
Fully Vested | Treadmill Rucking Hits Equinox
Weighted rucking just went luxury. Equinox just launched Fully Vested, the world’s first treadmill rucking program, complete with the high-performance Precision Vest.
Now at select Clubs and the EQX+ App, the program combines incline walking with strategic loading to, boost endurance with low impact, spike metabolism, build posture and resilience.

Cymbiotika | Liquid Colostrum
Colostrum—nature’s first food—just got a 2025 upgrade. Cymbiotika’s Liquid Colostrum delivers gut, immunity, muscle, and skin support in the most bioavailable form yet. Pure. Potent. Essential for athletes pushing their limits daily.
Neuro | Extra Strength Energy & Focus Gum + Mints
Launching today at 11AM PST: Neuro’s amped-up Energy Gum and Mints—packing 100mg natural caffeine per piece, plus L-theanine and B vitamins. Same refreshing peppermint and spearmint flavors. New bolder look. Same science-backed energy you trust.
Hormbles Chormbles | Protein Candy
The name’s wild, the product’s wilder. Hormbles Chormbles are protein-packed candies designed to satisfy your sweet tooth and fuel your gains. A disruptive new player in functional snacking.
Ciele Athletics | FSTCap Elite - Ethereal
Ciele is rewriting the technical running cap. The FSTCap Elite – Ethereal debuts a whole new form factor—lighter, faster, and built for elite performance. A Spring 2025 collection standout.
Sorsoap | Recovery You Can Scrub In
Recovery meets hygiene. Sorsoap crafts soaps shaped like recovery tools—or level up with the SORTOOL Pro, a portable muscle scraper that glides effortlessly pre, post, or even mid-workout. DIY recovery just got way easier (and cleaner).
✈️ Jet Lag Is A Choice
The only jet lag solution trusted by pro athletes, Navy SEALs, and world travelers.
Combines supplements, circadian science, and blue light glasses to reset your body clock and reduce inflammation caused by flying.
Helps eliminate fatigue, improve sleep, and boost immunity—so you feel great wherever you land.
