Been working pretty hardcore now with diet 85% percent, I do lat pulldowns on my back day on the hammer machine, usually will do 10x140lbs for 2 sets but Im geting no where and dont see any gains in my laterals....what else can I do? Last night for lats I tried doing 2 sets of 5x230 for more mass but not sure If this will pull better results...what else can I do to see Improvement?
