It's the first time that I have used a treadmill with "incline programs", and it was pretty cool to have the incline automatically change up and down while I walked. My old-dead Precor just had a hand crank for changing the incline.
It's the first time that I have used a heart meter too. It has one in the hand grip.
Last year, my walks in the park were about 5 miles each. I need to get my legs back into shape.
