Thanks for the input. I think the danger here is when lifters see this and then decide, oh well this makes sense...I'll use it for ALL my exercises! Then things like grip strength may go by the way side.
I do think even an intermediate lifter can benefit by doing this on one or just a few of their exercises. I for one am not nearly an advanced lifter; however, I will likely make Thibs pulldowns a part of my back training from now on.
