Using the platform part of the BOSU during the plank allows you to further
challenge your core as opposed to the floor plank in which your feet are on a
stable surface. This and other core exercises can be done during many different
kinds of workouts. Core workouts are an especially good time to use core
exercise progressions such as this
BOSU ball
exercise. You can increase the difficulty further for this or any other
plank by placing weights on the back or wearing a weighted belt although these
methods may not be best for everyone.
