Achilles is one of the most famous warriors in Greek mythology.
It is rumored that he was dipped into the river styx as a baby and had the weakness around his heel because that was the part of his body that was not actually dipped into the river.
Now, the idea of the Achilles heel is the weakness found within great warriors and athletes that will be their downfall or demise.
In CrossFit you are only as strong as your weakness. It does not allow you hide behind your other skills and strengths.
