So a set of reverse wrist curls will build a broad, thick powerful back?
AJ claimed is was so as the indirect effect as he called it
I was able to add size to my arms at one point by Training them only, but I added nothing to my chest or back
so it didn't work lke that for me
I'd say you need direct stimulation
now watch for that shitstain fat turd mac to post that same dumbass pic of me and never post any of my true muscle shots
he even tries to claim they arent me, what a turd he is lol
