Most lifters rarely feel the individual regions of their back working. You may have never felt your mid-back experience excruciating tension. Let's change that so your rhomboids and mid-traps can grow thicker. Try this:
Cable Mid Back Pull-Aparts
Flare your elbows and squeeze your shoulder blades together at the end of each rep.
It's not quite a row and not quite a pulldown. It's a hybrid that directly pulls in the direction of the rhomboid fibers. Cramping is normal if you're not used to this. Enjoy that.
Let's cut the bullshit and get to the brass tacks. For decades, men built slabs of muscle with simple, three day-per-week training programs. They trained their whole bodies in one brief workout session and they grew big and strong. Scoff all you want, but tens of thousands of trainees can't be wrong.
