Overtraining for long periods of time is bad. Short-term, planned overtraining, however, can be a massively powerful tool.
Functional overreaching is essentially short-term overtraining where you have a goal of digging yourself into a recovery ditch.

Doing so allows you to benefit from the harder training as your body gets a chance to recover.
