If you're going to put a treadmill in your room, make it a Spazio Forma. This top-of-the-line folding treadmill takes less than a square meter when folded and allows you to do cardio safely and effectively. It can adjust speed and gradient automatically based on your heart rate, which is measured via the telemetric band supplied. A handy mounting system keeps any tablet vertically or horizontally in place without covering the camera; it's perfect for Skype or games like the Goji Play. Unlike many treadmills, the large display is easy to understand and simple to operate. The price reflects the amount of engineering that goes into it.
