Dual medicine ball push ups can be for increasing the demand for shoulder
stabilization because of the round surface of the medicine balls or it can be
used to increase the range of motion of the push-up due to the height of the
medicine ball. Whether you are using these dual medicine ball pushups as a
stabilization, strength or bodybuilding exercise they are just as, if not more
effective than regular push-ups even if the medicine balls are being used simply
as push-up stands.
