Except "power poses" do work. I experience a marked increase in my energy and confidence when taking a "power pose".

Moreover, the "power pose effect" is a subset of the general experience that posture changes mood. The opposite effect can also be observed. Try exaggeratedly slouching. It produces a near-immediate decrease in energy and confidence.

Perhaps hormone levels do not change, but the subjective difference is (for me at least) undeniable.

Take it for granted for a moment that posture affects mood. In that case, how do we interpret a failure to reproduce? Could it be a case that they were not testing exactly what they thought they were testing, but that the folk-knowledge of posture is still correct?
