Cues are images, not anatomy

Nobody can voluntarily move their navel to their spine. The cue is an image intended to produce a particular abdominal action, and it works for some people and not others.

This is why teachers offer several cues for the same thing. If one does not land, a different image often does, and there is nothing wrong with you if the popular one does nothing.

Common cues and what they are asking for

Most of the standard vocabulary maps onto a small number of actual requests.

Common cues translated

Zip upPelvic floor and lower abdominal engagement
Ribs downStop the lower ribs flaring forward
Grow tallerLengthen the spine rather than compress it
Shoulders away from earsStop shrugging; let the scapula settle
Soften the kneesDo not lock the joint
Wring out the lungsFully complete the exhale

Ask when a cue does nothing

If a cue produces no change in what you feel, it has not landed. A good teacher will offer a different one rather than repeating the same words more emphatically.

Asking is normal and useful — it also tells the teacher something about how you process instruction.

Tactile cues

Many teachers use light hands-on cueing, which is often far more effective than words for position. Consent is the norm and you can decline at any time without explanation.

If touch is not welcome, say so at the start rather than mid-exercise — good teachers will simply use verbal and visual cues instead.
