Treadwall

If you thought the exercise machines at the gym looked intimidating, then think again as there's a new product based on mountain climbing and treadmills.

Instead of having you extremely high in the air like most climbing walls, the Treadwall makes sure climbers are never 1-2 feet off the ground. Since you're at a pretty safe height, there's no need for harnesses or any other sort of equipment. You just stretch, hop on and climb!

The Treadwall is also extremely simple to use. Climbers can adjust their rate of ascent and climbing angle with a twist of knob or turn of a wheel. Since the fitness machine stops and goes as you climb, you barely need any experience.
