Everybody knows that climbing can be a great workout for their legs- but setting up a climbing wall in the house is not really an executable idea! Enter the Treadwall. Treadwall is an innovative workout machine that provides you with four foot wide mounting area, which is very similar to a treadmill. The only difference is that you climb instead of running. If you are not fascinated with a vertical climb, go for the Pro model, which lets you incline and decline effortlessly!
