Seashell, those ATF hip thrusts are the same thing. Those are great. ATF just means ass to the floor, so if you do some squats or front squats ALL THE WAY DOWN. That will help.
Can you squat down, feet shoulder width, ATF, arms out in front of you, shins vertical (straight up and down, 90* to the floor), and not lose your balance? You could work on just that. Some of the hip flexibilty is also dependent upon flexibility in the lower back. It's all connected up in there. lol
