I have the vidoes of the Stone Warrior and the Iron Budhha.
I have compared them to the few versions of the Iron Wire I have.
I found them lacking in comparison.
Isokinetic exercises ( Dymanic tension through the full range of motion) are great to give you that "little something more", but I have found that very few people actually put that near maximal effort to truly reap the benefits and the longer the set the less intense it is.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
