Now let me start by saying this is a nice treadmill and would recommend it to anyone wanting a nice little machine to do low-intensity cardio on. Maybe you want to walk/job while you watch Tv, in that case, this is a great choice. It's a little noisy but not unbearable and overall gives a smooth walk. Also, be known that this treadmill isn't really meant to be run on for high-intensity cardio. You can try, but you may not have the best experience. Walking and jogging are better suited for this tSee full review
