Bought a used treadmill a few years ago. Good for a few miles a day. As I stepped up the intensity I realized I needed to step up my machine. The 7.0 has been great. Comfortable to run on.
I have found the feel of running on our 7.0 AT treadmill very similar to running in the road. This is very important to me as I prefer to run outside but our AT has made running on a treadmill much more enjoyable for me!
