Rock climbing has always been around, but has become quite popular in recent years. It’s a fun, great way to stay in shape, and has spawned all sorts of great variations of rock walls.
The latest comes to us in the form of a treadmill rock wall fittingly called the Treadwall. Just as the name sounds, this device is basically a treadmill and a rock climbing wall built into one. The contraption is quite large, but still much smaller than an actual wall for areas where space may be a bit more limited. The device spans 6 feet x 11 feet and can be used as both a freestanding or wall mounted unit. [Via]
