Whatever muscles you exercise will be your strongest muscles. I remember growing up watching professional wrestling. The well balanced wrestler stood up with a solid muscular build the top of the head to the bottom of the foot. Other wrestlers in worse shape appeared to have never seen the inside of a gym.
But there were wrestlers who had arms that were rock solid showing that they had diligently worked their biceps. However their bellies showed that they couldn’t remember the last time they completed a sit up or crunch. These wrestlers did not have a balanced approach to their exercise routine.
