if I see a single so called "communist" out there whose lats are not just poppin, whose torso is not just fearsome, shaped like motherfucking bruce lee, with biceps strong enough to rip apart the police by hand, I'll know they're actually a fucking LIBERAL
There is a tiny bit of pec activation in pulling exercises like rows, and it can be increased by using a supinated grip, like with a chin up. Not nearly significant enough to replace pushing exercises though.
