The NASM CPT7 Study Guide defines a force-couple relationship as the coordinated action of multiple muscles working together to produce movement around a joint. This occurs when muscles pull in different directions to produce the same rotary motion.

This coordination is essential for efficient movement patterns and injury prevention.
