So, what works in TCMA?
That depends on what you are "working at" right?
In terms of fighting what works is ANYTHING that you train to fight with. ie: anything that you train hard/full contact VS a resisting opponent and you can make work.
IN terms of the other things that TCMA is good for ( exercise and such), anything that you enjoy doing is something that you will do more often than something you do NOT enjoy doing.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
