You do not have to be strong to do Martial Arts.
There. It has been written. Without a shadow of a doubt, my opening sentence is true, and true in all cases. As you continue reading, you may feel your fury rising at something I have put forward as an opinion. If this happens, you can go back to the first sentence, take a deep breath, read it again, and enjoy being Right.
You. Do. Not. Have. To. Be. Strong. To. Do. Martial. Arts.
But, being strong is pretty fucking useful.
