as Evo says, press vs. push means two different muscle groups are being used.
in this case, they are antagonists. for pressing, your chest does the work, but the back stabilizes the chest. vice versa for rowing.
in fact, some people think its smart to warm up the lats with some rows prior to bench pressing, so the lats allow a better ROM for the chest. researchers have tested explosive force between rowing warm ups and non-rowing warm ups and found a slight increase in force in the rowing group.
