Cooling interventions can increase the amount of work or number of repetitions with the same weight during strength training, sometimes requiring an increase in sets.

“So from one day to two or three days later with cooling, he doubled the total work volume.”

“And what's very clear from the palmer cooling work is that by simply holding onto a cool object, remember not an object so cold that it constricts the vessels of the palms or constricts the vessels on the bottoms of the feet, but by holding onto a relatively cool object in one or both hands in between sets for two minutes or so, you can very efficiently reduce your core body temperature and in doing so, reduce the temperature of the muscles that are doing the work, increase the capacity for pyruvate kinase to continue to allow your muscles to contract and thereby allow you to do more volume of endurance and strength training.”

“You might get some weird looks, but of course you'll be the one doing significantly more volume, not experiencing delayed onset muscle soreness and achieving better endurance and strength gains were you to do this properly.”

“For instance, over six weeks of pull up training, palm cooling in between sets improved volume by 144%, and this was in experienced subjects.”
