As you advance in your exercise program, single movements may not only become
physically easier, you will get bored with them as well. These medicine pushups
stability crunches are basically 3 exercises in one. All 3 combined exercises
can be performed in a large set which may be the entire chest and core workout
if you are using a full body training split. Since this
set/exercise primarily involves the medicine ball push-up and the
stability ball crunch, both
exercises should be mastered before putting them all together.
