Subjects using palmar cooling were able to perform approximately 180 pull-ups in a fixed timeframe, nearly doubling performance compared to no cooling.

“And by doing this repeatedly over several sessions, over several weeks, they quickly went in the cooling group from a maximum of somewhere between 180 and 200 as I recall, I'm sort of estimating now, to 600 pull-ups in the equivalent amount of time which is absolutely incredible.”

“Then they came back and did the cooling. They did it the very next day which if you've ever trained a muscle, the very next day typically you wouldn't do as well in its training if it took any damage from the previous session or you at least do as well, but you probably wouldn't do what they then observed, which was, they started after every other set, the person would just hold the cold tube, cool down the body after every other set, rest everything else was kept the same and they found that they went to 180 pull-ups, which is incredible, it's a near doubling.”
