Mastered the Blank Slate? Time to move on to bigger and better things. Basically a vertical treadmill with climbing holds tacked to it, Treadwall is like climbing an infinitely tall, angle-adjustable wall without the risk of falling.

Just set the speed and climb – at least until your body gives out.
