Wondering what lower and mid back workouts you guys thought worked best for yall.my upper back is coming along nicely but im not seeing much result from the midpoint down? I was doing t-bar rows and bent over rows but my new training partner says that they will make me thick around my waist so i backed off??Plus he dont do deads?? so whatcha think? I really want to work on more of a v-shaped taper while adding more definition. any thoughts??
