Why your squats/deadlifts hurt your back (and how to fix it)


If you’ve ever thought…

  • “Why does my back ache after squats?”
  • “Why am I leaking when I deadlift heavy?”
  • “Why does my core still feel weak even though I’m strong?”

The missing link isn’t MORE core exercises. It’s HOW you’re breathing and how your ribcage + pelvis are stacked when you move.

Here’s the breakdown (and I’ve got 3 short videos for you below to SHOW you what I mean):

1️⃣ Your ribcage + pelvis have to STACK.

If they’re out of alignment, your diaphragm can’t do its job and your core + pelvic floor can’t engage the way they’re designed to. That’s when pressure leaks into your belly (hello DIASTASIS) low back (hello BACK PAIN) or pelvic floor (hello LEAKING+ unnecessary TENSION).

2️⃣ The BONES of your pelvis actually need to MOVE . (CLICK HERE TO SEE IT IN ACTION)
When your glutes + posterior pelvic floor are too tight, instead of the sacrum moving naturally, the whole pelvis just dumps forward. Cue: back pain, leaking, or diastasis.

3️⃣ Breathing is the foundation for lifting.
We need a 360° breath into the ribcage, low ribs coming back, and an “emptying from the bottom up” to set the stage for pressure management while we move.

Now let’s put it into practice:

🎥 Video 2: Supine 90/90 breathing drill (with towel)

🎥 Video 3: Breathing in the squat (finding your stack + internal rotation + glute length)

This isn’t about “perfect posture.” It’s about giving your body the mechanics it needs so you can move weight without pain, protect your pelvic floor, and actually get stronger.

👉 If this clicked for you, this is just ONE of the pillars I cover in Strong AF Foundation. Inside, we go way deeper into breath, position, strength training, and building a body that actually works for you (not against you).

This past week I sent my 7 and 9 year old off on their first day of 2nd and 4th grade. The bus came back, they got off safely, and I was able to exhale a little. Not every mom was that fortunate. It’s no wonder moms are anxious—it’s hard NOT to carry unnecessary tension in our bodies! If I could teach all women ONE thing when it comes to strength training and their pelvic floor, it would be how to hinge well. Why? Because when you learn to hinge… You protect your low back (instead of...

A couple weeks ago, I joined my good friend Jordan Syatt on his podcast. And the response has been incredible. Women from all over have been writing in to share their stories: “I almost cried a couple times. I felt seen.” “I finally feel encouraged that I can improve things without having surgery.” “Listening to you made what I am experiencing feel less humiliating.” “I’ve been trying to keep up with everyone—and that’s exactly what got me here.” “I have been having so much trouble with...
