What Diastasis Recti Actually Is
Diastasis recti is when the two sides of your ab muscles separate along the middle, leaving the connective tissue between them (the linea alba) stretched and weak. It’s incredibly common after pregnancy, and it can also show up from years of pressure being managed the wrong way. Here’s the part most workouts miss: the gap isn’t just about the muscles pulling apart. It’s about pressure. Every time you brace, lift, or crunch, pressure builds inside your belly. If your deep core and pelvic floor aren’t managing that pressure, it pushes forward against the weak midline. That’s what makes the gap bulge, cone, or dome. So the goal isn’t to avoid movement forever. It’s to stop pushing pressure the wrong way while you rebuild the system that’s supposed to hold it.
The Exercises To Avoid (For Now)
These moves spike pressure against the midline before your deep core can control it. If you have a gap that still cones or bulges, skip these until you’ve rebuilt your foundation: Crunches and sit-ups. The classic culprits. Curling up forces your abs to bulge outward against the exact tissue you’re trying to heal. Full front planks and push-ups. Held too long or too soon, they load the midline and often cause coning right down the center. Watch your belly, not the clock. Bicycle crunches and V-ups. Fast, twisting, loaded ab work stacks pressure and rotation on a midline that isn’t ready. Double leg lifts and leg lowers. Lowering both legs while lying down is a huge pressure demand; most cores will dome to manage it. Heavy lifting with breath-holding. It’s not that you can never lift. It’s that gripping and holding your breath drives pressure straight down and out. Exhaling on effort changes everything. Deep backbends and big overhead reaches that flare your ribs. Rib flare switches your deep core off and lets pressure escape forward. The test isn’t the exercise name. It’s your body. If your belly cones, domes, or bulges along the midline during a move, that’s your signal to stop and regress. No coning is the rule.
What To Do Instead
Rebuilding a gap is about the right moves in the right order, not more ab work. Here’s the progression we teach, from the inside out: Start with breath. Inhale and let your belly and pelvic floor soften and expand. Exhale and gently draw up from your floor and in through your low belly. This reconnects the deep core system that actually closes a gap. Five slow rounds is a real workout at this stage. Add gentle deep-core activation. Think heel slides, small leg marches, and connected exhales. These are moves where you can keep the midline flat and controlled the whole time. If it cones, make it smaller. Progress to supported strength. Once you can keep control, you build load slowly: carries, bird-dogs, and standing core work that trains your middle to brace under real life without bulging. The theme throughout: your deep core learns to manage pressure first, then you add challenge. Skip the foundation and even “safe” exercises can push the gap. Build it in order and your body starts holding pressure the way it’s designed to.
How To Know It’s Working
You’ll feel the connection before you see the change. Members tell us the first sign is picking up a car seat and feeling their middle brace on its own, or getting off the floor without doming.
The gap narrowing and feeling firmer under your fingers comes next. Measure by function first. Can you move through your day without holding your breath or bracing for the strain? That’s the win that lasts. This is exactly the path Core Corrective walks you through, step by step, so you’re never guessing which move is safe today.
The Bottom Line
The diastasis recti exercises to avoid all share one thing: they push pressure out through a midline that can’t yet control it. Skip crunches, sit-ups, full planks, and anything that cones your belly, at least for now. Rebuild from the inside with breath and deep-core work, then add strength in order. You’re not broken, and you didn’t miss your window. This is common and it’s fixable at any stage. This is not aboutweight. It’s about strength, healing, and long-term wellness.
Frequently Asked Questions
What Exercises Should I Avoid With Diastasis Recti?
Avoid crunches, sit-ups, bicycle crunches, V-ups, full front planks, push-ups, double leg lifts, and heavy lifting with breath-holding. Also skip deep backbends and big overhead reaches that flare your ribs. Any move that makes your belly cone, dome, or bulge along the midline is one to regress or skip for now.
Do Planks Make Diastasis Recti Worse?
They can. A full front plank held too long or too soon loads the midline and often causes coning right down the center. Watch your belly, not the clock. If it domes, come down. Modified planks against a wall or on your knees are a safer starting point once your deep core is reconnected.
Can I Fix Diastasis Recti Without Avoiding All Exercise?
Yes. You don’t stop moving. You change which moves and in what order. Rebuild with breath-led deep core work first, keep the midline flat, then add load gradually. The goal is training your core to manage pressure, not avoiding activity forever.
How Do I Know If An Exercise Is Safe For My Gap?
Watch your midline during the move. If your belly stays flat and controlled, it’s likely fine. If it cones, domes, or bulges along the center, make the move smaller or skip it. Your body’s response is a more reliable guide than any exercise list.
Is It Too Late To Fix My Gap If It’s Been Years?
No. There is no window. Diastasis recti responds to smart, in-order training years, even decades, later. The tissue and deep core can reconnect and strengthen at any stage, including perimenopause.
