Romanian or stiff-leg deadlifts with a band are excellent for "grooving" the hip hinge pattern and waking up your glutes and hamstrings before deadlifting.
Use this exercise as part of a warm-up for 2-4 sets of 10-20 reps. Or use it as a high-rep finisher. Time how long it takes you to complete 100 reps and then try to beat your time in the next workout.
You're doing your mobility drills and foam-roller work, but you're still in pain. If that sounds like you, maybe you need "muscle activation training."
