What is straight-leg raises to the inside?

Straight-leg raises to the inside

1. Lie on your side with your affected hip on the floor.
2. You can either prop up your other leg on a chair, or you can bend that knee and put that foot in front of your other knee. Do not drop your hip back.
3. Tighten the muscles on the front thigh of your bottom leg to straighten that knee.
4. Keep your kneecap pointing forward and your leg straight, and lift your bottom leg up toward the ceiling about 6 inches. Hold for about 6 seconds, then lower slowly.
5. Repeat 8 to 12 times.
6. Switch legs and repeat steps 1 through 5, even if only one hip is sore.
