Adductors (for some also hamstrings)
Take a seat next to the wall and swing up your legs up the wall. Allow your legs to relax out to either side, without pushing the legs as far as possible. Just relax and allow your legs to stay where you feel your first edge, some tension and resistance.
There´s not one way to do this pose. Feel the target area, and modify the pose until you feel the target area, and can allow your muscles to relax.
Stay around 2-5 minutes. Then slowly ease out of the pose by bringing your legs together.
