What is a defining feature of compound movements?

A defining feature of compound movements is that they involve multiple joints and muscles. This characteristic allows compound exercises to engage various muscle groups simultaneously, promoting overall strength development and functional fitness. By utilizing multiple joints, these movements mimic real-life activities and can enhance coordination, athletic performance, and muscle synergy. For instance, exercises like squats, deadlifts, and bench presses recruit numerous muscles and joints, making them efficient for building strength and burning calories.

The other options suggest characteristics that do not align with the nature of compound movements. Isolating a single muscle group is more indicative of isolation exercises, which focus on one specific muscle without engaging others. Using light weights typically applies to beginners or rehabilitation contexts and is not a defining characteristic of compound movements, which can be performed with a range of weights depending on the individual's level. Lastly, performing movements in a static position refers to exercises that do not involve joint movement and are not representative of compound movements, which are dynamic and involve multiple joints in motion.
