The video tutorial demonstrates an exercise involving arm circles to warm up the shoulders, core, and obliques. The exercise is performed by holding the ball out straight and making big circles with the arms, first in one direction and then in the opposite direction. This helps in warming up the shoulders and core muscles, including the obliques.
