Hip drive: I love RDLs, I give them to the majority of my clients and do them myself. However, some people have a hard time with the hip drive.
You will see this with clients who have a weak posterior chain(glutes, hamstrings, calves) and will often compensate with their low back, devastating for a golf swing.
In this exercise we target the hip drive by placing your feet away from the wall, going into a hip hinge (leaning forward), then thrusting your hips forward. If someone has a hard time with the hip drive, they may stumble forward or fall back into the wall.
To make this harder, move your feet away from the wall.
