This video shows a hip exercise which combines hip rotation and abduction.
If you are unable to view the video, here is a still sequence of the exercise -
|Lie on your side with your head supported. Lift the top leg so that the feet are a handsbreadth apart.|
|Maintain the feet in this position while you roll the top knee outwards, opening the space between the knees.|
|Relax back to the starting position, keeping the feet apart and the knees apart.|
|Repeat the external rotation from this abducted position.|
|Repeat the sequence 10 times.|
