About a year ago, I learned how to climb a rope. As an adult. No PE nostalgia. Just me, a length of rough rope, and some very bruised shins. I started with the mechanics of the J-hook and the S-wrap. These foot locks are the "efficiency hacks" of the rope; they allow your legs to do the heavy lifting while your upper body guides the way. When it clicks, it feels simple: wedge, stand tall, slide the hands, repeat. But then there is the legless climb with no borrowed leverage.
