After my first back surgery thirteen years ago I needed to do a lot of walking. For me it was easier to have it handy in the house instead of going outside, especially in the bad weather. I purchased a Weslo Cadence 1015 Treadmill at that time. It has everything I need to monitor the heart, calories burned, miles ran, time, and speed. In all this time I just replaced the bateries for these programs to work. Now how is that for a great product giving lasting service? Another great thing about this treadmill is it can be raised to attach a storage latch which lets you store it in a flat position to take up less floor space. Over all this is just a great machine.
