Define core stability, body part isolation, spotting

Core stability: This refers to the ability of the muscles of the core (abdominal, back, and pelvic muscles) to support the spine and maintain a stable trunk position during movement or while holding a static posture. Good core stability is essential for efficient movement and injury prevention.

Body part isolation: This is a training technique where exercises are designed to target and work a single muscle or muscle group as much as possible, minimizing the involvement of other muscles. This is often achieved through specific movement patterns or by using machines that restrict movement to one plane.

Spotting: In weightlifting, spotting is the act of assisting someone during an exercise, typically with free weights, to ensure their safety and help them complete repetitions. A spotter provides support if the lifter struggles or fails, preventing injury and allowing them to push their limits.
