Specific Warm-Ups

A specific warm-up will constitute any work that bridges the gap between the general warm-up and the working sets. 

This may be present in your program as neurologically based movements (such as single leg hip thrusts before RDLs) or even pre-exhausting movements before your first heavy compound exercises (like leg extensions before hack squats).

But be careful with overuse of Specific Warm-Ups, as doing so can negatively impact your performance by the time you get into your working sets.
