Everything these days that can be customized seem to catch on faster than a stock version, and the Precor AMT 100i fitness trainer falls under such a category. It allows you to get to your workout regiment on the spot without having to worry about pushing any buttons to change movements or adjusting the contraption according to your body build and shape. This is made possible as the commercial grade cardio fitness product is smart enough to adapt itself to individual body sizes and fitness goals, delivering a low impact, high intensity workout. Changes of its movement path from elliptical, treadmill to climbers can be achieved without having to push a single button. Sweat it out in peace now, eh?
