Because your at-home training should be enjoyable, ProForm built a spacious deck so you don't feel cramped when you walk, jog, or run. The 60-inch length allows your legs to extend out your stride. The 20-inch breadth provides more elbow room for your upper torso. The combination of these two measurements gives you plenty of space to move around in while still being close enough to the machine that you aren't isolated from each other. The deck is also elevated slightly which makes you feel less like you are working out in an area where people can see you. Instead, it feels more like you are working out inside of a cave or closet where nobody can bother you. Finally, the deck is adjustable so you can change the height it takes up during different times of the year. In the summer, you might want it to be lower so you can enjoy being outside longer. In the winter, you could raise it up so it doesn't interfere with your workouts while still giving you the ability to take advantage of outdoor tracks and sidewalks. These are just some of the many reasons why we think people love using their proform treadmills as far away from home as possible.
