I used to do low stance work, good solid work.
I am talking with a weight vest even and sometimes a partner on my shoulders.
I thought that was real tough.
Then a did a 20 rep squat program and died.
For those of you that don't know, a 20 rep squat set is where, after you warm up for a couple of sets, you do 20 reps with a weight that you can only do for 10 reps.
Yes, you heard me.
Then you collapse, puke, crap yourself and die.
Lots of things seem tough, until you do tougher.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
