Final answer:
The push up with one arm row involves movements in the sagittal, coronal, and transverse planes due to the combination of upper body stabilization, pushing, and rowing motions required for the exercise.
Step-by-step explanation:
The push up with one arm row involves movements in multiple planes of motion. The push-up portion occurs primarily in the sagittal plane, involving flexion and extension motions at the elbow and shoulder joints. The one arm row portion engages the shoulder, requiring both abduction and adduction which occur in the coronal plane, as well as medial and lateral rotation of the limb at the shoulder, which involves the transverse plane.
Furthermore, stabilization of the scapula is crucial during this compound movement, involving the muscles of the pectoral girdle to maintain proper alignment and motion.
