“If your core training doesn’t make you better at the things you actually do — lifting, running, bending, picking stuff up — you’re training the wrong thing.”

Myth #1: You Need to Do Crunches to Have a Strong Core

Crunches are terrible. And I mean that in the most technical way possible.

Here’s what happens when you crunch: you’re flexing your spine while your core does almost nothing. Your rectus abdominis — the visible ab muscle — flexes your spine. That’s its job. But a functional core does something completely different. It stabilizes your spine while your body moves around it. Those are two entirely different muscles and two entirely different movements.

I had a client about three years ago — guy in his mid-40s, ex-athlete type — who’d been doing 50 crunches every morning for two decades. Absolutely shredded abs. Could barely deadlift 185 pounds without his back rounding. His core wasn’t strong. His rectus abdominis was strong. His actual core — his transverse abdominis, his obliques, his deep stabilizers — was basically asleep.

When we switched him to ab wheel rollouts, dead bugs, and anti-rotation work, his deadlift went up 45 pounds in eight weeks. His abs didn’t go anywhere. But his spine was finally protected.

The research backs this up. A 2023 study in the Journal of Strength and Conditioning Research found that anti-rotation exercises produced significantly better carryover to functional movements than traditional flexion exercises. Translation: the stuff that feels “harder” actually works better.

Myth #2: Core Training Means Training Your Abs

Your core is not your abs.

Your core is a complex system. It includes your transverse abdominis (deep layer, acts like a corset around your entire midsection), your rectus abdominis (what shows), your obliques (internal and external), your erector spinae (runs along your spine), your multifidus, your pelvic floor, and your diaphragm. That’s a lot of moving parts.

But here’s what the internet sells you: ab exercises. Ab workouts. “Six-pack abs in 30 days.” Because abs are visible and they sell supplements.

A truly functional core? It’s about integrated stability. It’s about your body resisting unwanted movement while allowing wanted movement. It’s about bracing. It’s about tension.

That’s why pallof presses work so well. You’re holding a weight at chest height and fighting rotation. Your core has to resist movement that’s trying to happen. Or dead bugs — you’re lying on your back, moving opposite limbs, and keeping your spine from arching off the floor. Your deep stabilizers are doing all the work. Your abs? They’re barely involved.

That number isn’t random. It means most back pain isn’t about lack of ab visibility. It’s about lack of stability.

Myth #3: You Have to Train Your Core 5-6 Days a Week

Nope.

Your core isn’t a separate muscle group that needs its own dedicated day. It’s a stabilizer. It supports everything else you do. Train your squats, your deadlifts, your rows, your presses — those all demand core stability. Do that three times a week with solid form and you’ve already trained your core.

But here’s where most people mess up: they do heavy compound lifts with terrible tension. Loose spine. No bracing. Then they add “core work” on top of it, wondering why their back still hurts.

Real talk: if your compound lifts are solid and you’re adding 10-15 minutes of intentional core stability work 2-3 times a week, you’re ahead of 95% of people. That’s it. Pallof presses. Dead bugs. Planks with good tension. Maybe a weighted carry or two. Three weeks in you’ll feel the difference in your everyday life — picking things up without thinking about your back, sitting with better posture without effort.

One of my clients, woman in her early 50s, was doing 45 minutes of core work three days a week. Absolutely obsessed with it. Still had lower back pain. We cut it back to 12 minutes, twice a week, and focused on actual heavy compound lifts instead. Back pain gone in four weeks. Now her core is actually strong because her whole body is integrated.

Myth #4: Floor Exercises Are the Only Way to Train Your Core

The internet is obsessed with floor work. Crunches, planks, sit-ups, dead bugs, mountain climbers — all on the floor.

And yeah, some of that works. Dead bugs are legitimately great. But you’re missing something if that’s all you do.

Your core needs to resist movement in multiple planes. And you can’t do that lying on your back.

Pallof presses force your core to resist rotation. Farmer carries force your core to resist lateral flexion. Suitcase carries, bird dogs with rotation, landmine rotations — these train your obliques and your deep stabilizers in ways floor exercises just can’t touch.

Plus, functional life doesn’t happen on the floor. You bend. You lift. You rotate. You reach overhead. You should train that way.

At Aura Heaven, we stock equipment designed for standing core work — ab wheels, suspension trainers, and resistance bands that let you train anti-rotation, anti-lateral-flexion, and anti-extension movements. That’s what actually transfers to your life.

Myth #5: A Strong Core Means You Can See Your Abs

Abs are visible. Strength is invisible. These are not the same thing.

You can have visible abs and a weak core — which is exactly what my 40-year-old crunch guy had. You can also have zero visible abs and an absolutely bulletproof core. Core strength is about stability, tension, and function. Visible abs are about body composition and genetics.

Here’s what actually happens: you get strong. Your movement improves. Your posture improves. Your back pain goes away. Your lifts go up. And if you also happen to eat in a way that lets you see your abs, that’s separate. That’s diet. That’s body composition.

I see this with clients all the time. They’re frustrated because they’re doing all the “ab work” and their abs still aren’t visible. Turns out they’re eating at a 200-calorie surplus and their core is actually getting stronger, but they expected to see it. That’s not how it works.

What Actually Works: The Three-Exercise Core Protocol

After eight years of coaching, I’ve narrowed it down. Three exercises. Two to three times a week. 10-15 minutes total. This works for almost everyone.

This protocol works because it hits anti-extension, anti-rotation, and anti-lateral-flexion in ways your body actually understands. Three weeks in, you’ll notice you’re bending differently. Your posture is taller. Your back feels better. That’s not placebo. That’s actual neurological change.

Questions I get all the time

Do I need equipment to train my core?

Nope. Dead bugs, planks, bird dogs, and pallof presses (with a door anchor and a band) work great with zero equipment. But if you have access to it, an ab wheel is one of the best core tools ever invented. Forty bucks and it lasts forever.

How long until I see visible results?

Three weeks for strength and stability changes you’ll feel (posture, bending, breathing). Six to eight weeks for visible changes (assuming you’re eating right). If you’re looking for visible ab definition, that’s entirely about diet.

Should I do core work every day?

No. Two to three times per week. Your core is not a separate muscle group — it recovers like everything else. And if your main lifts are solid, you’re already training it enough. More isn’t better here.

What if I have lower back pain?

Start with dead bugs and pallof presses. Skip loaded carries until the pain settles. And honestly — if it’s serious pain, see a physical therapist first. I coach around issues, not through them.

Are planks actually useful?

Yes, but only if you’re doing them right. Most people do sloppy planks for 60 seconds and think they’re training their core. One minute of solid tension beats five minutes of garbage. Use planks as a warm-up or a finisher, not the main event.

Can I get abs if I don’t do ab exercises?

Absolutely. Abs are visible when you have low enough body fat. Diet handles that. Heavy compound lifts (squats, deadlifts, rows) build core strength. Ab-specific exercises? They’re optional once you understand that your core strength comes from stability work, not flexion work.

How do I know if I’m doing an exercise correctly?

The golden rule: if it feels tense in the right place, it’s probably right. Dead bug tense in your core and lower abs? You’re winning. Pallof press feeling like you’re fighting rotation? Yes. If you’re not sure, shoot a video and compare it to form breakdowns. And yeah, it’s worth asking a coach in person once.

Should I do ab wheel rollouts?

They’re phenomenal. But they’re hard. First two weeks will feel terrible. By week three it suddenly stops feeling like dying. If you’re a beginner, start with dead bugs and pallof presses for four weeks, then add rollouts. But seriously, they work incredibly well.
