Pilates blah blah blah Core Strength blah blah blah blah blah Pilates blah blah blah Core Strength bladdy bladdy blaaaaaah
Yawn.
Google “pilates core strength”—you’ll get 1,040,00 entries. By the time I finish writing this post, there will be more.
I’m not trying to be flip, but it is hard to keep a fresh perspective on something that is everywhere.
Let me be clear: I love Pilates. I practice it myself, I own a studio, I teach my 72 yr old mom how to master an articulating pelvic bridge every time I go home (you rule, mom!). If there is a Pilates cheerleader, I am the archetype clutching the pom poms.
My problem, however, is that most people have a distorted concept of what muscles constitute the core.
Last June, the NY Times published “Core Myths” (http://bit.ly/bXhH7S), an article which highlights the risks of simply “drawing your belly to your spine.” The author rightfully argues that the spine is like a fishing rod surrounded by core-supporting muscles that act as guy wires, and strengthening any one of these muscles in isolation could throw things out of whack.
But the article didn’t clearly define the core. Instead, it referenced “all the major muscles that girdle the spine.” Okaaaaay, but WHAT are those muscles? The transversus abdominus (deepest corset-like abdominal layer), the multifidi (small spinal stabilizers), and…drumroll…the PELVIC FLOOR.
Huh? What is that? And why is it rarely, if ever, mentioned when referencing the core?
NEWSFLASH: WE DON’T TALK ABOUT IT BECAUSE WE ARE EMBARRASSED.
Let me break it down for you:
The pelvic floor is a hammock of muscles that lies between your pubic bone, cocyxx bone, and ischial tuberosities (those two bony nubs you can feel when you are sitting cross-legged on the floor). Other terms people use to describe this area include: loins, groin, pubic area, crotch. This hammock of muscles not only supports your bladder, rectum, and reproductive organs–as if that weren’t important enough– but it also works synergistically with your other core muscles (transverse and multifidi) to support the action of the spine.
It surprises me that many highly-educated & fit people don’t know about the importance of the pelvic floor, which is effectively the bottom of the cylinder of your torso. If the cylinder’s bottom isn’t strong, its overall structure becomes compromised, right? Here are some metaphors to help you consider the pelvic floor’s importance:
- Imagine building a gorgeous house on a weak foundation. Bad news.
- Imagine lifting a soggy paper bag that’s filled with groceries. Yikes.
- Imagine any cylindrical container carrying precious cargo, and then imagine that it’s missing its bottom. Ruh-roh.
You get it.

I understand it can be uncomfortable to talk about openly, especially in the context of exercising. You wouldn’t bat an eyelash if your trainer told you to draw your belly to your spine as you lift a heavy weight. But if she told you to gently contract your pelvic floor as a way to further stabilize your pelvis, you might be confused. So you ask her to clarify and suddenly you’ve fallen down the rabbit hole of awkward as she references the muscles that surround your genitalia.
Here are your options:
Ignore your pelvic floor and lose out on an important ingredient in building core strength (not to mention easier childbirth, improved intercourse, preventing incontinence down the road, etc)
OR
educate yourself and figure out a way approach pelvic floor strengthening in a way that feels realistic to you. (If the phrase “imagine contracting your vaginal muscles” makes you giggle and feel awkward, then ask your instructor to use a code word instead. One of my client’s and I agreed on calling it “the goods”—whatever works.)***
LOCATE IT
There are many pelvic floor strengthening exercises. The first step is learning what the heck those muscles feel like—it’s hard to exercise a body part you can’t locate! Here’s a simple one: Try to draw your pubic bone toward your tailbone, then release it. Try this 10 times in rapid succession. (lift, release, lift, release, etc).
WORK IT
Once you feel like you get the hang of it, try to perform a simple upper abdominal curl while contracting your pelvic floor. On the exhale, curl your head and shoulder-blade tips off the mat, while a) drawing your belly to your spine and b) drawing your tailbone toward your pubic bone. Return your head and shoulders to the mat on the inhale. (It is key to let the pelvic floor release on the inhale. We don’t want to keep it indefinitely contracted.) Bravo! You have just contracted your core muscles three dimensionally (your multifidi automatically contract when you engage your transverse).
RESEARCH IT
Enough from me and my pelvic soapbox. Take it from the experts.
Here are two good pelvic floor books. Both highlight the anatomy of the great down under, and offer practical strengthening and stretching exercises.

(I’m not gonna lie: the former has some funky photos, and the latter has aa risque cover. I made a circa 2nd grade book cover for it so I can read it in public without getting funny looks).
***Important: If any of the following situations apply to you, please see a specialist: any post-natal discomfort, a history of PFD (pelvic floor dysfunction), incontinence, uterine prolapse or any chronic pain in your pelvic floor. Many people can benefit from pelvic floor relaxation as opposed to contraction, so research your specific condition carefully.
