Imagine a severely hypoflexible person. In the piriformis stretch (a.k.a. the yoga "pigeon pose"), is it better for the stretched hip, femur, and knee to fully contact the ground, tilting the torso sideways towards the stretched hip,
or support the inflexible hip with a yoga block so as to keep the torso in line (more or less) with the stretched femur?
p.s. I believe I overstretched my knee joint doing neither of the above. This "third method" is not recommended.**** you yoga.
