What is a primary characteristic of a compound exercise?

A primary characteristic of a compound exercise is that it involves multiple joints and muscle groups. This type of exercise is designed to engage several muscle groups simultaneously, which can lead to increased strength, coordination, and functional fitness. For example, the squat or deadlift utilizes the legs, core, and back, promoting overall stability and strength by necessitating the coordinated action of multiple muscles.

Engaging multiple joints means that compound exercises often mirror real-life movements, making them effective for functional training. They are particularly beneficial for developing strength and muscle mass, as they typically facilitate heavier loads compared to isolation exercises, which focus on a single muscle group. This approach is advantageous for athletes and overall fitness enthusiasts looking for efficient workouts that maximize time and effort.

While it's true that some exercises can target specific muscle groups or can be performed with body weight and various types of equipment, those aspects do not define compound exercises. Therefore, the heart of what makes a compound exercise distinct lies in its multi-joint and multi-muscle involvement.
