To help demonstrate why that needs to be fixed, here’s how that plays out. When you have lost the link between your pelvic floor and your TrA, your body skips over the pelvic floor contraction as you exhale, going right to the TrA and multifidi contraction. But those contractions are weak, disorganized contractions. Then you continue on, firing the outer abdominal muscles, then moving your arm or leg, firing the outer abdominal muscles more in response to the arm or leg movement and then, finally, at long last you’ll have a late, really strong contraction of your pelvic floor.2,7 It fires really hard to make up for being so late, but often it may be a day late and a dollar short if you’re prone to leaking, especially if that arm or leg movement was lifting a heavy stroller into the trunk of your car. Or maybe trying to do so while laughing.

This pattern needs to get fixed. That disorganized TrA contraction means you’re missing out on thousands of times a day when you could be getting a high quality, functional core contraction. If you’re doing planks and wondering why they’re not helping, this is why. Planks in your workout don’t hold a candle to missing out on thousands of contractions a day that should happen naturally. Don’t get me wrong, keep working on your planks, but work on your firing pattern too. If you’re working on your Kegels and you know your pelvic floor is strong, but you’re still experiencing leaks or accidents, it could be a firing pattern issue. If you just don’t perform athletically the way you want, it could be because you aren’t getting those core muscles to fire the way they ought to. It’s like the difference between doing a push up on a BOSU ball versus on firm ground. You just won’t have as much power without a stable base.
