There is much talk of isolation exercises not being functional.
I have to disagree.
Whenever I’ve done cable chest flyes my bench increases.
I have a feeling that cable lateral raises serve in much the same way for shoulders, shoring up useable strength, and largely contributing to the look of “hollywood muscle”.

Curls, such a blasphemous thing to the “serious” trainer – to them I ask are pullups serious? – as curling, most strikingly on a preacher curl machine very clearly improves the ease in which I do pullups and my rep max at the same.
I say isolation movements are functional.
