The Romanian deadlift, or RDL, is a great exercise for glute and hamstring development, but its resistance curve is in a descending pattern. So when the glutes are pushing through to finish hip extension, they're not working against a lot of resistance.
This can be remedied with bands of course, but what works even better is using the Hammer Strength shrug/deadlift station. Due to the way these machines are designed, the resistance curve is greatest at the top of the movement. When you use it for your RDLs your glutes and hams have to generate a lot of tension from start to finish.
