The weight of a medicine ball is determined by the thickness of the material (rubber). The heavier it is, the larger the diameter. [Features] In addition to general muscle training, medicine balls can also be used to train the core. Muscle training trains your abdominal muscles to create a ``slit belly'', but ``training your core'' means strengthening the deep muscles (inner muscles) that support the ``pelvis, spine, and shoulder blades'' that form the skeleton. It means to train. [Training manual included] A basic training manual (with illustrations) was created under the supervision of an athletic trainer.
