If you have a bench, get your mrs or a training partner to sit on your legs as you hang off the end from your hips and do the RH movement. You might need to increase its height somehow, or add weight to get the desired affect. I use a RH with high reps, good mornings, and stiff leg & Romanian style deadlifts for my lower back/core. Don't neglect the obliques and abs too. Oh and hip thrusts/Glute bridges (weighted or un-weighted) are cool too. Go single legged for more variation.
