You’re probably doing it wrong. Honestly, most people are. You see them at the gym every single day, butts hiked up toward the ceiling or lower backs sagging like an old clothesline, shaking uncontrollably while they stare at the timer on their phone. They think they’re "crushing it" because they held the position for three minutes. They aren't. They’re basically just hanging out on their ligaments and putting a massive amount of unnecessary shear force on their lumbar spine.
The correct way to plank exercise isn't about time. It’s about tension.

If you can plank for five minutes straight without breaking a sweat, you aren’t actually planking. A real, high-tension plank—the kind that professional athletes and physical therapists actually care about—should make you want to quit after about thirty seconds. It’s a full-body contraction, not a passive pose. We’ve been lied to by "30-day challenges" that prioritize duration over quality, and it’s time to fix that.
Stop Thinking About Your Abs for a Second
Wait, what? Isn't a plank an ab exercise? Well, yeah, but your "abs" (the rectus abdominis) are just a small piece of the puzzle. When we talk about the correct way to plank exercise, we’re talking about the entire anterior chain. This includes your obliques, your transverse abdominis, your glutes, and even your serratus anterior—those finger-like muscles on your ribs.
Dr. Stuart McGill, arguably the world’s leading expert on spine biomechanics and author of Low Back Disorders, has spent decades studying this. He doesn't advocate for the "marathon plank." Instead, he pushes for something called the "Russian Kettlebell Challenge" style or the "Hardstyle" plank. The goal here is maximal stiffness. You want to turn your body into a literal piece of reinforced concrete.
If someone tried to push you over from the side while you were planking, you shouldn't budge. Not an inch. Most people are so loose in their setup that a gentle breeze would knock them over.
The Anatomy of a Perfect Setup
Let’s get tactical. Forget the clock. Get on the floor.
First, look at your elbows. They should be directly under your shoulders. Not way out in front, and not tucked back toward your hips. If your elbows are too far forward, you’re putting a weird leverage demand on your rotator cuffs. If they’re too far back, you’re losing the ability to drive through the floor.
Clench your fists. Seriously, squeeze them. There’s a principle in neuromuscular physiology called irradiation. When you strongly contract one muscle, it helps "recruit" neighboring muscles. Squeezing your fists actually helps your shoulders and chest engage more effectively.
Now, look at your feet. Most people keep them wide because it’s easier. It provides a wider base of support. If you want the correct way to plank exercise to actually challenge your deep core, zip those legs together. Feet touching. This immediately makes the exercise more unstable, forcing your adductors (inner thighs) and your pelvic floor to wake up and join the party.

The Secret Sauce: Posterior Pelvic Tilt
This is where 90% of people fail. They have "banana back." Their pelvis is tilted forward (anterior tilt), which creates a deep arch in the small of the back. This "shuts off" the abs and puts all the pressure on the spinal discs.
To fix this, you need a posterior pelvic tilt. Think about tucking your tailbone between your legs. Imagine you’re trying to pull your belly button up toward your chin, or better yet, try to bridge the gap between your ribcage and your pelvis.
Why the Glutes Matter
You cannot have a perfect plank with soft glutes. It is physically impossible. Your glutes are the anchors of your pelvis. If they aren't squeezed—and I mean squeezed like you're trying to hold a hundred-dollar bill between your cheeks—your lower back will eventually take the hit.
In a study published in the Journal of Orthopaedic & Sports Physical Therapy, researchers found that conscious engagement of the gluteals and the abdominal wall significantly reduced the load on the lumbar spine during prone bridges. Basically, if you don't squeeze your butt, you're just wearing out your spine.
Is a Forearm Plank Better Than a High Plank?
People argue about this all the time. The truth is they serve different purposes.
The forearm plank (low plank) generally allows for more isolated core tension because you're closer to the ground and have a shorter lever arm. It’s harder on the abs. The high plank (on your hands, like the top of a push-up) involves more shoulder stability and tricep engagement.
- Low Plank: Best for raw core strength and learning pelvic control.
- High Plank: Best for "functional" carryover to movements like push-ups, burpees, or mountain climbers.
- Side Plank: Essential for the quadratus lumborum (QL) and obliques.
If you aren't doing side planks, you’re missing half the story. Dr. McGill’s "Big Three" exercises for back health include the side plank specifically because it targets the lateral stabilizers of the spine without the high compressive loads of other exercises. It’s the "missing link" for people who have great "six-pack" strength but "weak" backs.
Breathing: The Forgotten Element
Don't hold your breath.
I know, it sounds counterintuitive. You’re trying to create tension, so you want to brace. But there is a difference between bracing and "Valsalva-ing" (holding your breath until your face turns purple). If you hold your breath, your blood pressure spikes and you'll fatigue in seconds.
The correct way to plank exercise involves "bracing behind the breath." You should be able to maintain that rock-hard abdominal wall while taking short, sharp "sips" of air. Think of your core like a pressurized canister. If you let all the air out, the canister collapses. If you over-pressurize it without venting, it bursts. You want to maintain that internal pressure while keeping the oxygen flowing.
Common Mistakes That Are Killing Your Progress
- Looking at the wall: People love to look up at the TV or the mirror. This puts your cervical spine (neck) into extension. Keep your gaze down at your thumbs. Your neck should be a neutral extension of your spine.
- The Shoulder Shrug: If your shoulders are up in your ears, your traps are doing the work. Push the floor away. Imagine you're trying to grow longer through your armpits.
- The "Slow Death" Sag: As people get tired, their hips slowly sink. The second your hips drop below the line of your shoulders and heels, the set is over. Stop. Rest. Do it again. Junk reps don't build strength; they build bad habits.
Variations That Actually Work
Once you've mastered the basic correct way to plank exercise, please stop trying to hold it for ten minutes. It’s a waste of time. Instead, make the move harder.
The Saw: From a forearm plank, use your ankles to rock your body forward and backward. This changes the lever length dynamically and forces your core to react to changing forces.
The Long-Lever Plank: Move your elbows further out in front of your head. This increases the torque on your midsection exponentially. A two-inch move forward can make a 30-second plank feel like an eternity.
Three-Point Planks: Lift one leg. Or one arm. Suddenly, your body has to fight "anti-rotation." Your obliques will have to fire like crazy to keep your hips from dipping to one side. This is where real-world core strength is built.
Let's Talk About Results
Why do we do this? Is it just for a flat stomach?
Not really. A plank is a "foundational" movement. It teaches your brain how to move your limbs while keeping your spine safe. Whether you're picking up a heavy grocery bag, swinging a golf club, or carrying a toddler, you need your core to be a stable bridge.
If that bridge is weak, the force leaks out. We call this "energy leaks." If you're a runner and your core is weak, your hips will wobble, your knees will cave, and you'll end up with shin splints. If you're a lifter and your core is weak, you'll never hit a heavy squat PR because your back will fold.
Practical Steps to Master the Plank
Forget the ego. Start over. Even if you've been "planking" for years, go back to basics.
First, set a timer for 20 seconds. Only 20. But for those 20 seconds, I want you to give 100% effort. Squeeze your fists. Squeeze your glutes. Pull your elbows toward your toes (without actually moving them) to create "lat" tension. If you aren't shaking by second 15, you aren't trying hard enough.

Second, do this 3 to 5 times. Rest for 30 seconds between rounds. This "cluster" approach builds much higher quality motor patterns than one long, sloppy set.
Third, record yourself. Use your phone. You’ll be shocked. You’ll think your back is flat, but the video will show a massive dip or a "piked" hip position. The camera doesn't lie.
Fourth, integrate "anti-movements." Once the static plank is easy, try to maintain that perfect form while someone (or yourself) adds a small distraction, like lifting a hand to tap a water bottle in front of you.
The correct way to plank exercise is a skill, not just a workout. Treat it like a practice, like a martial art or a golf swing. Focus on the nuances—the tilt of the pelvis, the tension in the quads, the depth of the breath. That is how you build a core that isn't just for show, but one that is actually bulletproof. Stop counting the seconds and start making the seconds count.
Get on the floor. Tighten everything. Breathe. That's the secret. No fancy equipment or 10-minute timers required. Just you versus gravity, and if you're doing it right, gravity should be winning a lot sooner than you're used to.
