Scale up or down as needed in weight and reps. New exercisers do 2 reps with lighter loads ( or bodyweight only) that you can easily manage. by 10th rep, last two reps should be difficult but able to be completed with proper form.
If not sure of 1 rep max, simply begin with a comfortable weight and increase load as needed.

3x12 BB or DB Hip Thrusts w/elevated feet on chair or box (30 second rest)
