A:Answer Great question! The Treadmill BXT8J is great for both walking and running :) When it comes to comparing treadmills, Continuous Horsepower (CHP) ratings fail to paint the complete picture. The motor is simply one component of a complex mechanical system in which each part plays a role in the overall experience. Additionally, your home’s wall outlet and your treadmill’s internal breaker place a limit on the maximum power output that your treadmill motor can sustain. This limitation results in about 1.8 or 1.9 HP with typical motor efficiency regardless of whether your motor can continuously output 2.5 HP, 3.0 HP, 3.5 HP, or more. Motor warranty length, maximum belt speed, and maximum user weight are better indicators that you are purchasing a treadmill with a reliable and powerful motor. - Bowflex Team
