Aunts Treadmill

My Aunt has a motorized treadmill, I've always wanted to try one out, so I tried hers and dang does it feel intense. When I went on it, it wasn't moving fast enough, so I pushed the increase speed button, which really didn't do much, then I pushed about 20 times rapidly and boy did it speed up, I was almost a victim like you see in some of those videos you see online.
