In a study from the Sporting Goods Manufacturers Association (SGMA), more people said treadmills were their favorite piece of aerobic exercise equipment over any other kind. In 1996, consumers spent $1.4 billion on treadmills, one third of the entire fitness market, according to SGMA, and that dollar mark is even higher today. According to treadmill reviews and comparisons in the Journal of the American Medical Association (Source: JAMA, Volume 275, May 8, 1996), The Proform Space Saver model is the optimal indoor exercise machine and the best for aerobic fitness With this sort of review is it any wonder why the Proform Spacesaver Treadmill is currently the most popular treadmill for home use? I think not. What consumers say most is that they love how it can sit against a wall and the treadmill can be folded up and out of the way. This makes it especially good for fitness conscious people with limited space in their home. When they fold the treadmill down and start their workouts they are even more impressed. Doctors recommend low or reduced impact running and walking to help reduces stress on the knees, hip joints and ankles. The Proform Spacesaver Treadmill does just that. In fact the The ProForm Space Saver treadmill features Cushion Deck" technology - a layer of durable cushioning directly under the tread-belt which significantly absorbs impact and helps users to exercise more with less chance of damage to their joints. The average home treadmill running deck is only 14 to 16 inches wide and users complain about the sway this allows when using them. The SightLine Series Proform Space Saver model has been equipped with an expansive, 20-inch wide, 50-inch long tread-belt- allowing users more freedom to move naturally during their workout with less sway from their natural body movements Did you know that virtually 100 percent of treadmill owners surveyed said they watch TV during treadmill workouts , according to Tele-Source, an independent research group. In the past home users had to turn their treadmill around to get away from staring at a wall to be able to watch TV while working out. The Proform Spacesaver Treadmill addressed and solved the issue by designing a reverse, fold-down feature. This allows the user to fold down the treadmill walking area and be automatically facing the middle of the room, so they don't have to turn it around like other models.
