Precor's Adaptive Motion Trainer is a cardio exercise equipment. It's a hybrid of an elliptical machine, a treadmill, and a stepper that can replace a treadmill and provide you additional alternatives in your workout to keep things fresh. The AMT provides a variety of levels of difficulty so you can adjust the workout to meet your needs. It also has built-in music storage so you can listen to your favorite tunes while working out. The AMT also has web access which allows you to watch videos on fitness topics from Precor and other popular sites. The AMT can be used as a standalone unit or it can be attached to your existing home gym with its universal joint system. You can use it for low-intensity work such as walking or running or you can use it for more intense workouts such as sprinting or jumping rope. Since it replaces the need for a traditional treadmill, you avoid the risk of injury associated with this type of exercise. The AMT is easy to use and stores away quickly so it's perfect for people who want to add some variety to their workout program.
