Exercising on a Precor AMT - adaptive motion trainer - is like running and climbing on air! There is no track or ramp that guides your motion, it is up to you what shape the motion is and you can change it anytime you want, simply by moving your body to change your stride shape. There are no mechanical changes needed or console buttons to push. The AMT® goes from short to long strides, walking to running, and climbing to lunging. Users can change their workouts smoothly, easily, and spontaneously, just by moving naturally.The motion can instantly be like stepping, cycling, elliptical, climbing, jogging, running or anything in between. It is very smooth, no impact, bio-mechanically correct and fun! Your perceived exertion is lower that running on a treadmill or using the elliptical, but you are actually burning more calories!
