Why install a rock climbing wall in your house when you can purchase the Treadwall. This device is a 4 foot piece of equipment that allows you to climb using the same characteristics as a treadmill. If climbing up a vertical wall is too hard for you, you will be able to adjust the incline or decline of the machine to fit your capability. Although no price tag has been attached to this great invention, you can hope that the price will not cost an arm or a leg.
