The next time you’re somewhere non-embarrassing, try this quick test: stand on one leg with your arms stretched out to the sides, imagining that one hand is holding a rock. Next, the tricky bit: “pass” the rock overhead to your other hand without putting your leg down, then pass it back, and repeat the whole movement 10 times without losing your balance. Don’t worry if you can’t manage it: that means you’ve got something to work on.
Dan Edwardes, one of the UK’s most experienced coaches in the athletic obstacle-leaping discipline of parkour, calls this the “rock pass” drill – and says it’s one of the simplest ways to check up on your proprioception, or your body’s sense of where it is in space. Sometimes referred to as our sixth sense, proprioception is what helps high-level athletes take a penalty without looking at the ball, or orient themselves in the air while doing a twisting somersault. But it’s also what lets you touch your nose with your eyes closed, push open a door without shoving it too hard, or adjust your gait when you hit an unexpected root on a trail run.
