>>i think you are missing my point...ie when i need to "balance my chest" (pectorals) against my back, a push up is not gonna cut it...i walk over to the bench press and start stacking weights on...and for the pull upss...same thing...start stacking weight...
I got you now... that is one way to see the training, my experience tells me that this training does work for me and my students (we do 3 months of rock climbing in PE), I guess it might work for others.
