Compound movements refer to exercises that involve multiple joints and muscle groups working together in a coordinated manner. These types of exercises typically target larger muscles, such as those found in the legs or back, and can help improve overall strength, power, and endurance. Examples of compound movements include squats, deadlifts, bench presses, rows, and pull-ups. By engaging multiple muscle groups at once, these exercises provide a more comprehensive workout that can help build lean muscle mass and improve overall physical performance.
