The running surface and cushioning system should also be considered carefully. A comfortable belt gives you enough room to walk or run naturally without constantly worrying about stepping too close to the edges. Runners may prefer a longer deck because it provides more space for a full stride, particularly at higher speeds. Cushioning is equally important because it can make workouts feel more comfortable compared with running on harder outdoor surfaces. However, cushioning should not make the treadmill feel unstable or excessively soft. When possible, try the treadmill before purchasing it so you can evaluate whether the belt feels smooth, stable, and comfortable while walking and running. picking a treadmill for a home gym
