24 Weeks Pregnant: Abdominal Muscle Smarts—Supple vs. Steel

“My body’s strength and flexibility reflects my inner strength and flexibility.”

There’s lots of talk about core strength—but what does this conversation look like when your belly is growing, expanding, and changing during pregnancy? For many of us, core strength is sought when, in fact, core flexibility may be needed. The Spinning Babies® perspective promotes function and health above the focus on strength. In this case, we define a healthy core as being supple, fluid and long.

Overdevelopment of the abs without matching the flexibility and function of the back and buttock muscles can lead to pain and diastasis recti. Releasing the psoas is essential—more on the why and how of psoas release below.

Your choice of exercise during pregnancy can either promote or help prevent diastasis recti (DR)— separation of the front abdominal muscles. To help keep DR at bay, ditch the planks, crunches, and heavy lifting. Instead, try pelvic tilts, bridge pose, and side planks that strengthen your obliques. Listen to your body and keep one knee down to start and for as long as that feels best.

When engaging your core, draw your belly in, rather than allowing it to cone or push out.
If attending exercise classes, be sure your instructor has specific prenatal training.

Spinning Babies Activity of the Week

The psoas is a large pair of powerful muscles located behind the abdominals. They attach at your spine between the pelvis and the ribs, then wrap around to the front of the pelvis and drop down to attach at the top of the thigh bones. They help us walk upright and support our abdominal organs. Taoist traditions call the psoas “the muscle of the soul.” The tone of the psoas can affect baby’s position and descent during birth.

Liz Koch of Core Awareness is our favorite psoas expert, so we defer to her here. A contracted psoas can lead to low back and hip pain in pregnancy. Liz explains that the psoas doesn’t need strengthening, but needs releasing and awakening. You can practice psoas releases daily.

Psoas Lengthening with Constructive Rest Pose

  1. Gather a yoga mat, bolster or couch cushion, and a couple of yoga blocks or other pillows.
  2. Create an incline: On a yoga mat, place one yoga block in its tallest position and another at its longest position, perpendicular to the first block. Or use several a few pillows to create a lower and upper level. Rest a bolster or couch cushion over the two blocks or pillows. Sit with your bum directly in front of the bolster and lie back. Keep the knees bent and the feet flat on the mat, hip-width apart.
  3. Begin to focus on your breath. Inhale into the side ribs to stretch the diaphragm (ditch your bra if wearing one). With every exhale, imagine the thighbones getting heavier and sinking deeper into the hip sockets. The more the thighs can sink, the more the psoas is encouraged to relax into the back body where it belongs. Repeat for 15 breaths.
  4. Allow your pelvis and spine to remain neutral—no tucking.
  5. Rest here for 10 minutes.
  6. Keep expanding your diaphragm by breathing into the side ribs (expanding your ribs to each side). Notice your thigh bones slowly releasing lower. The hip sockets relax. This helps the psoas.

Your Baby This Week

Your baby now weighs about 1.3 pounds and is almost 12 inches long. Deposited skin pigmentation means baby’s skin is becoming less translucent. Meanwhile, unique hand- and footprints are also forming.
