i seem to hear two different points of view on this so im a little confused. probably a case of too much thinking, not enough doing.
-on one hand you have people/articles giving the thumbs up for weighted crunches, side bends, hypers, and other such twists, bends and so forth.
-on the other hand you have people/articles stating the core is designed to be stable and not mobile, and is best worked through lifts such as squats, deads, farmers, and other such lifts where movement is minimal around the core.
so which would it be? would one style build more strength and the other more size? or is it just a preferance of what type of workout you prefer? they seem to contradict one another, one stating thecore shouldnt be worked through movements and the other stating it should. any insight?
