Hip opener yoga poses for people with tight hips. It’s tricky to set them up so they are not compromising their knees and lower backs. Often times gravity fed poses (poses that require resisting gravity-such as pigeon) need to be adjusted so they are not stretching with the weight of their body, rather, they are using their own controlled force to move into the stretch. Such a modification would mean having the client lay on their back in the same pose, just in reverse, and use their arms to draw their leg in, rather than having them lean their entire body weight into the pose to accomplish the same thing. Less risky.
