Big Friday is a term used in athletic populations (predominately strength athlethes) to describe the final training session subsequent to a weekend of recuperation. Big Friday is usually (but not exclusively) a heavy or tough training session where the goal is to achieve a big training performance, however it is also associated with strong intent and focus towards the final training session regardless of what weight is prescribed in the training session.
