The most common system of resistance training used with dynamic exercise against constant or variable resistance is progressive resistance exercise (PRE). A later section of the chapter, which covers systems of training using mechanical resistance, addresses PRE.
Dynamic constant external resistance (DCER) exercise is a form of resistance training where a limb moves through a ROM […]

The intensity of exercise in a resistance training program is the amount of resistance (weight) imposed on the contracting muscle during each repetition of an exercise. The amount of resistance is also referred to as the exercise load (training load), that is, the extent to which the muscle is loaded or how much weight is […]
