Muscular failure
Muscular failure is the point in a set where another rep cannot be completed with valid technique. It is distinct from technical failure, which arrives earlier: that is when form breaks down even though the weight still moves. Training to failure maximises fibre recruitment within that set and also the fatigue it leaves for the ones after it.

In practice
The sensible use is selective: the last set of an isolation lift, where the fatigue cost is low. On heavy compounds, failure buys little extra stimulus and charges a lot on the sets that follow.
The common mistake
Prescribing it on every set and then counting them as ordinary volume. A client training to failure throughout tolerates considerably fewer weekly sets, and a plan that does not discount for it digs a hole in three weeks.
