Essential Treadmill Buying Guide

Essential Treadmill Buying Guide: "Most home treadmills allow you to create a hill effect by changing the incline up to a 15% grade. You want to check for manual incline adjustment only (stop the belt, get off and make the adjustment), push button power incline, and programmable incline which would allow you to program different inclines into your workout. High end treadmills have an automatic incline feature that will change the incline during the workout to increase or decrease your desired heart rate."
