This is the Treadwall, a vertical treadmill by Brewer’s Ledge. It’s not for running, it’s for climbing. Orrrrr just run on it for all I care. It’s your life! The climbing area measures about 8 feet high, 4 feet wide. The thing’s got adjustable inclines and declines so you can really challenge yourself. Go hard! Me? I like to take it easy. I’m talking like, laying down and taking a nap. While this thing seems waaaaay cooler than a regular horizontal treadmill, it also seems like the chances of experiencing a humiliating situation that gets caught on camera and sent in to America’s Funniest Videos are also waaaaay higher. And that’s really saying something because treadmill mishaps already make up nearly half of the clips on that show. The other half? Dads getting hit in the nuts and old people falling down.
