Summary
This episode covers the science of palmar cooling for exercise performance, explaining how cooling the palms (glabrous skin) can dramatically increase training volume and delay fatigue.
Key Points
- Palms, soles, and face have special blood vessels (AVAs) for heat exchange
- Cooling palms between sets can increase training volume by 50%+
- Temperature must be cool (50-60°F) not cold - ice defeats the purpose
- Stanford research shows 144% more pull-ups over 6 weeks
- DIY methods (cool water bottle) work nearly as well as expensive devices
- Cool between sets, not during
