Core Exercises to Avoid

As we discussed in Core Training: Start Here, proper core training can be the key to preventing pregnancy pains, facilitating an easier labor, expediting your postpartum recovery, and even creating a healthier fetal growth environment for your little one.  However, doing the wrong things could actually increase your risk of experiencing pains or injuries like Diastasis Recti or Pelvic Floor Dysfunction.  Learn the movements you’ll want to avoid or regress during the later stages of pregnancy and early postpartum period.

What to Avoid (or Regress)

The movements below are likely to create far too much stress on the core muscles, especially the external abdominal wall, during the later stages of pregnancy and early postpartum period when the deep core muscles are still weak.  Avoid (or in some cases regress) the movements below to help prevent core injuries like diastasis recti or pelvic floor dysfunction from becoming an issue:

1. Spinal Flexion: Movements that cause rounding of the spine (like the obvious sit-ups and crunches).

Spinal flexion also includes things like slouching, which many of us spend a lot of time doing…

It also include things like bending over improperly by rounding at your spine instead of hinging at your hips and maintaining a neutral spine on the way down.

2. Spinal extension: Movements in the opposite direction from above also create excess pressure, like back-bends or even full upward dog positions in yoga.

3. Lateral Spinal Flexion: Sideways bending of the spine like these oblique bends

4. Rotation with flexion or extension (twisting): OK this one deserves some clarification because not all rotation movements are bad.  Rotation is a fundamental movement pattern, and as humans, our bodies need to rotate.  So, let’s clarify what rotation is good, and what should be avoided.  Rotation with hips and shoulders in line is GOOD.  Rotation with disassociation of hips and shoulders (think bicycles) should be AVOIDED.  Watch the video below, which explains this concept a bit more and provides some sample good and bad movements.

5. Full Planks: If performed properly (with neutral alignment and proper core activation), planks can be fine before you develop an obvious belly, and once deep core strength has been restored postpartum.  However, if performed with a large belly OR weak deep core muscles, a plank places far too much downward facing pressure on the outer abdominal wall.  So, in the later stages of pregnancy and early postpartum period, regress planks by either placing your knees on the ground…

Or, better yet, performing them on an incline to add in some glute activation.

For many women, at some point in late pregnancy and early postpartum, all plank variations may have to be completely avoided.  Always watch the belly for signs of “bulging” (last point) as a key indicator of whether the movement is appropriate or not.

6. Full Side Planks: Even though these do not involve direct downward facing pressure on the belly, they are still advanced core movements that create excess intra-abdominal pressure, and will therefore likely need to be regressed.  See this effective alternative below: the side lift and lower plank:

7. Advanced Back-Lying Core Exercises: You may have heard the guidance that once you develop an obvious belly, you should avoid movements lying still and flat on your back.  This stems from the concern that the weight of the uterus could compress the main blood vessel that carries blood to the heart and therefore restrict blood flow to the fetus.  This was more of a concern in the past than it is now.  Today we know this is really only a concern for long periods lying still and flat on your back (like 8 hours sleeping at night), and even then your body will wake you up if there is an issue (which you can easily resolve by simply rolling to your side).  While we still advise being conservative, and avoiding most movements lying still and flat on your back, that is NOT the primary reason we recommend avoiding movements like the hollow body hold below (or other movements like leg lifts, v-sits, etc).  These movements should be avoided because of the sheer amount of pressure they place on the outer core muscles — with a pregnant belly or a weak deep core postpartum.

8. Any movement that causes “bulging” or leakage:  
If you ever perform a movement and notice a torpedo-like protrusion down the center of your abdomen (like the image below), this is a sign of diastasis recti, and a key signal the movement is not appropriate.  In the image below, the bulging you see is the woman’s abdominal contents protruding through her separation.  Similarly, if you perform a movement and you experience accidental urine leakage, this is also a sign the movement is not appropriate, as it’s indicative of a compromised pelvic floor (the “floor of your core”).

Now that you understand what NOT to do, be sure you understand what you should be doing. Begin by learning how to properly activate your deep core muscles.  This technique is essential for pregnancy training and postpartum recovery.  Once you’ve mastered this, you can move onto these beneficial core movements.
