Whether or not you see your FMA as a "stand alone" or "add-on" martial art, many FMA practitioners do practice it along with another art. I personally am amazed at how well the FMA I practice blends with what else I do. And interestingly, the other guys in my group agree, even though the other arts we each practice are very different... sometimes almost opposite by themselves. FMA has become the bridge that ties us all together. How about the rest of you? Do you train other arts? How does your FMA relate to what else you do?
