The most misunderstood cue in Pilates.
"Engage your core" might be the most repeated instruction in movement, and one of the least understood.
Most people respond to the cue by bracing, sucking the stomach in, holding the breath. None of that is what the cue is asking for.
The core isn’t one muscle flexed on command. It’s a system: deep abdominals, obliques, the diaphragm, the pelvic floor, all working together to support the spine while everything else moves freely around it. Bracing shuts that system down instead of switching it on. It also makes breathing harder, which defeats the point of almost every exercise built around it.
“The core isn’t engaged, it’s just tense. The two feel similar and produce completely different results over time.”
A better test: can you hold a plank and still talk in full sentences? If the answer is no, the core isn’t engaged, it’s just tense. The two feel similar and produce completely different results over time.
This is one of the first things corrected in every Pivot & Plane session, regardless of who’s teaching it or where it’s taking place. It’s a small correction with a large effect, exactly the kind of detail a rushed class doesn’t have time for.
