The hip thrust + leg curl combo exercise is a great accessory exercise for the glutes and hamstrings. It is much tougher than it looks. I am performing the single leg version, but start out using both legs.
Some key points:
1) Drive through the mid-to-back of your feet/foot as this will allow you to better target the glutes and hamstrings.
2) Before you lift, take a deep breath in and brace your core (keep your ribs down). This will stabilize your pelvis and spine and will allow you to generate strength with your lower body.
3) When you pick up your hips, do so with your glutes, NOT by hyperextending your back.
