I've heard that medieval style sword fighting is a good counterpart for computing. Swinging the rather heavy two hand sword loosens the shoulders nicely, the same can be said about the one hand sword and the shield.
Just an FYI, a longsword is only about 3lbs max (mine is ~53" OAL, with a 40" blade, fully two-handed hilt. Right at 3lbs). Some of the zweihanders got up to about 5-6lbs, but anything heavier than that is for hanging on the wall, not for practice or combat.
Being interested of the emerging aspects of historic swords and sword fighting it seems it starts to be represented on more public venues too. https://www.youtube.com/watch?v=4ZIsc6KPkKA&feature=youtu.be-C+
That is anything but historical.
Its a lot more interesting than formal fencing. I like that folks are keeping a martial art alive and they should be applauded. Maybe its not exactly the style some like...ok...but its all part of a larger discipline.
