Well first off, im in the process of totally changing my workout around because of some great advice i got earlier, but i wanted to address this problem that im having during back workout days. As i said a while back, I work out at home, but i do have a pulldown machine, usually i do my wide grip pulldowns and close grip pulldowns here, the problem im having is that sometimes i feel like my lats are never being worked (as you can see in my pictures) and only my biceps, ive tried arching my back, lowering weight, and a few other things but never can seem to get that "lat pump". I was wondring if there was any tips you guys could give me to maybe help me make sure im working my back, not my biceps totally.

Thanks
AL
