How is an incline less impact? The impact comes from the foot hitting the ground. No matter what the incline, the impact is going to be there. But the incline is just to get my heart rate up, that's all. Plus, it adds a little more challenge.
I think it just helps that the treadmill is so user friendly. It's got two fans on the treadmill, big wide sides, the Soft Run floor, and it's new. Plus lots of room for water and I can put a couple of books on there. I can't run at my other gyms... I tried it, and man was it uncomfortable. But at this gym, the treadmill is real comfortable. It doesn't hurt that it faces Navy Pier, and on a nice day, you can totally veg out and just stare out at the nice weather, clear skies, and the Pier.
