There’s always some form of posterior chain strengthening in every one of our programs.
We see a lot of individuals come to see us with issues that are commonly cause by poor posterior chain strength.
For athletes they may present with poor take off speed and poor jump height, and for general population clients they may present with back and knee pain.
We train them both the same way: Deadlifts - train the hip hinge movement first and then move to loading the movement with a bar Leg curl - lying, seated, standing, unilateral, etc. Back extension - different angles and varying overloads Reverse hyper - accumulate volume by doing these every session, especially with those suffering from lower back pain
