High effort and consistent practice in climbing are primary drivers of skill improvement, potentially more so than adjunct therapies like red light therapy.

“I mean because so much of climbing just comes down to effort when you're doing the thing. Like if you go climbing several days a week and you try your absolute hardest every time you're climbing, you're going to get pretty freaking good, you know, whether you do red light therapy or like any of the weird other stuff or not. So it's like I mean it really just comes down to your effort doing the thing.”
