Proper execution of the 90-90 QL opener produces a deep stretch in the lower back on the painful side extending into the hip, and should be held comfortably for about 30 seconds, repeated up to five times, with progression by building deeper into the stretch with each repetition.

“you know you're doing it right because you're going to feel a deep stretch on the one side of the lower back right here into that hip...hold this one comfortably for about 30 seconds...repeat this one up to five times and with each repetition try to build into it just a little bit more”
