Internal rotation refers to the movement of a limb or body segment around its long axis toward the midline of the body. This movement is essential in various physical activities and exercises, helping to maintain proper alignment and function of the joints involved. For example, when the shoulder is internally rotated, the arm moves closer to the body's center line.

Understanding internal rotation is crucial for personal trainers and fitness professionals, as it plays a significant role in improving athletic performance, correcting movement patterns, and preventing injuries. It is also important to differentiate internal rotation from external rotation, which involves moving a limb away from the body's midline.

The other options fail to accurately describe internal rotation. Outward rotation describes external rotation, which is the opposite movement. The specificity to lower limbs is misleading, as internal rotation applies to various body segments including the arms. Lastly, lateral movement does not align with the definition of internal rotation, which is focused on the angle of movement around the long axis rather than the plane of the body.
