It depends - If I've gone heavy on deadlifts and weighted chins I like to do some pullovers supersetted with shrugs to finish off.

But I'll probably only do that 1 in every 3 or 4 weeks

Same with chest really - After the basic heavy compound movements, there are so many different exercise to do that I'll pick and choose between them.

I've done pullovers for my chest then 2 days later done them for my back - you can definitely feel it on your chest but by minimising the strain on your chest your effectively working you back harder.
