You do 200 crunches a night and your core is still weak. Your lower back aches after deadlifts. You cannot hold a plank for 60 seconds without shaking like you are in an earthquake. The problem is not effort. The problem is exercise selection. Most people's ab routines are built around movements that barely challenge the core's actual function.

Here is what changes when you swap that crunch marathon for good core exercises: your squat gets more stable, your posture improves, your lower back stops complaining, and yes — the visible abs come too. But function first, aesthetics second.

Why Most Ab Routines Miss the Point

Your core is not just the rectus abdominis — the six-pack muscle everyone obsesses over. It includes your obliques, transverse abdominis, erector spinae, hip flexors, and diaphragm. These muscles work together to resist movement, transfer force, and stabilize your spine under load.

Crunches train spinal flexion. That is one function out of many. Good core exercises train anti-extension, anti-rotation, anti-lateral flexion, and hip flexion — the patterns your core actually performs during sports, lifting, and daily life.

Think about it: when you carry heavy groceries, your core is resisting lateral bending. When you sprint, it is transferring rotational force. When you squat 300 lbs, it is bracing against spinal extension. None of those tasks look anything like a crunch.

The 8 Good Core Exercises You Should Be Doing

1. Dead Bug

Lie on your back, arms extended toward the ceiling, knees bent at 90 degrees. Slowly extend your opposite arm and leg toward the floor while pressing your lower back flat into the ground. Return and switch sides.

Why it works: Teaches anti-extension under control. If your lower back arches off the floor, you have lost the rep. This is the foundation that every other core exercise builds on.

Programming: 3 sets of 8 per side. Slow and controlled. No rushing.

2. Pallof Press

Attach a band or cable at chest height. Stand perpendicular to the anchor. Press the handle straight out from your chest and hold for 2 seconds, resisting the rotational pull. Return slowly.

Why it works: Pure anti-rotation training. Your obliques fire hard to keep your torso from twisting. This translates directly to rotational sports and heavy compound lifts.

Programming: 3 sets of 10 per side.

3. Ab Wheel Rollout

Kneel on the floor with an ab wheel. Roll forward as far as you can without letting your lower back sag. Pull back using your abs, not your hip flexors.

Why it works: One of the hardest anti-extension exercises available. EMG studies show rollouts produce higher rectus abdominis activation than nearly every other core exercise tested.

Programming: 3 sets of 8-12. If you cannot do these from your knees without your back collapsing, start with plank variations first.

4. Farmer's Carry

Pick up two heavy dumbbells or kettlebells. Walk with tall posture, shoulders packed, core braced. That is it.

Why it works: Full-body core engagement under load. Your entire midsection fights to keep your spine neutral while you move. Simple, brutal, effective.

Programming: 3 sets of 40-meter walks. Go as heavy as your grip allows.

5. Hanging Leg Raise

Hang from a pull-up bar. Raise your legs to at least 90 degrees — ideally toes to bar — by curling your pelvis upward. Lower with control.

Why it works: Trains hip flexion with a posterior pelvic tilt, which is what actually engages the lower abs. If you just swing your legs up with momentum, you are training hip flexors, not core.

Programming: 3 sets of 8-12. Bend knees if straight legs are too difficult.

6. Suitcase Carry

Same as a farmer's carry, but with weight on one side only. Walk without letting your torso lean toward the loaded side.

Why it works: Anti-lateral flexion at its finest. Your obliques on the unloaded side work overtime to keep you upright. Most people have never trained this pattern and it shows.

Programming: 3 sets of 30 meters per side.

7. Bird Dog

From a hands-and-knees position, extend your opposite arm and leg simultaneously. Hold for 2 seconds at the top. Return slowly.

Why it works: Legendary spine researcher Stuart McGill included this in his "Big 3" for spinal health. It trains anti-extension and anti-rotation simultaneously with minimal spinal load.

Programming: 3 sets of 8 per side.

8. Copenhagen Plank

Set up a side plank with your top leg resting on a bench and your bottom leg hanging free. Hold the position while squeezing your adductors to keep your body in a straight line.

Why it works: Trains lateral core stability and adductor strength simultaneously. Research shows it significantly reduces groin injury risk in athletes. It is brutally hard and almost nobody does it.

Programming: 3 sets of 20-30 second holds per side.

How to Program Good Core Exercises Into Your Training

You do not need a dedicated "ab day." That is a waste of a training session. Instead, slot 2-3 core exercises into the end of your existing workouts.

A smart weekly layout:

  • After upper body sessions: Dead bugs, Pallof press, ab wheel rollouts
  • After lower body sessions: Hanging leg raises, farmer's carries, bird dogs

This gives you 4-6 core-specific exercises per week spread across your regular training. Combined with the bracing demands of compound lifts like squats and deadlifts, that is more than enough stimulus.

You can also do a quick core circuit at home on rest days. No equipment needed for dead bugs, bird dogs, and plank variations. A workout app can help you stay on track and progressively overload these movements just like you would a bench press.

The Visibility Question

Let's be honest — most people searching for good core exercises want visible abs. Here is the truth: ab visibility is 80% body fat percentage and 20% muscle development. You will not see your abs at 20% body fat no matter how many rollouts you do.

Get your nutrition dialed in and train your core with the exercises above. The combination produces a midsection that both looks impressive and actually works.

What About Planks?

Planks are fine for beginners. But once you can hold a plank for 60 seconds, it becomes an endurance exercise rather than a strength exercise. At that point, progress to harder variations — ab wheel rollouts, body saws, or long-lever planks — instead of just holding longer. A 5-minute plank proves you are patient, not strong.

The Bottom Line

Ditch the crunch obsession. Train your core for what it actually does — resisting unwanted movement and stabilizing your spine under load. The eight exercises above cover every function your midsection is built for. Do them consistently, get your sleep right for recovery, and you will build a core that performs as well as it looks.

Strong beats pretty. Luckily, these exercises deliver both.
