Should your ‘tuck your tailbone’ to work your core? No. Here’s why.
Here’s some stuff you may have been told as a kid in ballet class, or just last week by an exercise instructor… cues we have been hearing (and as instructors, taught to teach) for years about how to stand in ‘correct posture’ or how to ‘work your core’:
“Squeeze your butt”
“Suck in your stomach”
“Tuck your tailbone under”
If you’re following these kind of cues, then unfortunately you’re building yourself a fairly flat shaped backside, possible pelvic floor weakness and maybe ‘weak knees’.
Progressive programs like MUTU System don’t tell you to do that stuff… so you get the best workouts for your body!
Here’s a little ‘am I engaging TVA correctly?’ challenge for you instead – stand side on to that mirror, I want you to ‘engage your core’ WITHOUT moving your pelvis. It’s harder right?
Because ‘engage your core’ doesn’t mean, ‘suck your stomach in’ and it definitely doesn’t mean ‘tuck your tail bone under’ or squeeze your butt. It means drawing your belly button back VERY GENTLY (this really is a very subtle movement, not a forceful one – if you’re not sure, draw it back, then halve that), or imagining a line between your hip bones that you’re going to draw together… (yes, you should feel your pelvic floor lift when you do this – that’s good!)
Try not to let your pelvis tuck under. Breathe out, slow and steady and draw your belly button in…. but keep that natural curvature in your spine. It’ll feel at first like you’re consciously sticking your backside out.
