You should tilt your treadmill at least 30 degrees sideways and practice side hilling if you want a realistic workout. The only ones that simulate western hunting are the incline trainers that go up to 40% incline. 15% might seem like a lot until you hit your first steep, sustained pitch. Then you realize it wasn't close to what reality is.
