This activity is challenging multiple systems at once! From a motor control and neuroscience perspective, this task requires the brain to coordinate distal mobility (hands and feet) on top of proximal stability (core and pelvis). The core must activate continuously to keep the trunk stable while the arms generate force and the feet adjust position - this is known as anticipatory postural control, a key foundation for skilled movement. The activity also heavily engages the proprioceptive system,
