Overload and Isolation Exercises

[Countahab]

I know the principle of overload when applied to compound exercises involving the large muscle groups but does it still apply to the same extent for isolation exercises? I would have thought that there must be a limit to how much small muscles can grow so overload becomes ineffective after reaching a certain level. Must admit this is guesswork so advice from someone who understands exercise science would be welcome. I find isolation exercise weight seems to stick once a certain level is reached.

Yes it does apply to isolation exercises. Just in a smaller scale.

Besides squats, I consider everything else isolation exercises, so overload everything I do.
