I know that by saying this I may be in the minority but when I saw Cutlers back conditioning it reminded me of Yates. Grainy, ripped, sinew. He isnt Yates but his back has really become dominant. From 03 to 06 the transformation has been pure hard work by Cutler.
grainy back has nothing to do with hard work my friend,,it is the timing of your halotestin,,nutrition-carb load,,and ofcourse duretics,,those 3 factors and only those 3 factors will determine how grainy your back will look,,
