Clamshell

Lie on your side with your affected hip on the top. Keep your feet and knees close to each other without any gap and your knees bent such that your ankles are in line with your pelvis and your top shoulder.

Place a small pillow under your head and raise the bottom arm on the floor so that it rests on the pillow as you keep lying on your side.

Roll your pelvis a bit forward.

While maintaining the above position, slowly open your top knee while keeping your feet together. As you do this, try to engage your upper hip area, and let it initiate the motion. Your legs should resemble a clamshell as they open up.

Hold this position for a few seconds and then slowly lower down to the starting position.

Do 2 to 3 sets of 10 repetitions on each side daily. If you feel fatigued at any point, ease off and resume once discomfort settles down.
