The Fitness Industry Lied to You About Core Training

If your idea of core training is crunches, sit-ups and planks held for time, you’ve been sold a very small version of the truth.

The fitness industry loves exercises that are easy to demonstrate, easy to count and easy to package. Core training became about visible abs rather than functional stability. The problem is that your core was never designed to flex repeatedly on the floor. It exists to transfer force, resist movement and keep you stable under load.

When core training is done properly, it stops looking impressive and starts being brutally effective.

What the Core Actually Does

The core is not just your abs. It includes the deep abdominal muscles, spinal stabilisers, glutes, hips and the muscles that link the upper and lower body.

Its primary job is not to create movement but to control it. The core resists rotation, resists extension and stabilises the spine while the limbs produce force.

That means the best core training does not involve endless bending and twisting. It involves staying rigid while the rest of the body moves or while external load tries to pull you out of position.

Why Crunches Miss the Point

Crunches and sit-ups train spinal flexion. They do very little to prepare the body for real-world tasks. Carrying weight, lifting awkward objects, moving over uneven ground and absorbing force all require the spine to remain stable, not repeatedly flex.

Worse, excessive flexion-based training can increase spinal fatigue without improving load tolerance. You end up with sore lower backs and no meaningful increase in functional strength.

That’s not progress, it’s misplaced effort.

Real Core Strength Is Anti-Movement

True core strength shows up when movement is resisted.

• Anti-extension, preventing the lower back from arching under load

• Anti-rotation, resisting twisting forces

• Anti-lateral flexion, preventing side bending when weight is carried on one side

These qualities are developed through carries, bracing and loaded movement, not through chasing a burn on a mat.

This is why people with strong cores often don’t look like they train abs at all. Their strength is built through function, not isolation.

Load Exposes Weakness

You can fake a plank. You cannot fake a heavy carry.

When you add load, weaknesses show immediately. Shoulders shrug, hips shift, posture collapses. The body either learns to stabilise or the movement fails.

Weighted vests, rucks and offset loads force the core to work the way it was designed to. Stabilising the spine while breathing hard, walking, climbing or changing direction.

This is core training that transfers.

Carries Are King

If you want a simple, brutally effective core exercise, carry something heavy and move.

Farmer’s carries, ruck marches, front-loaded carries and uneven loads all challenge the core differently. They demand posture, breathing control and sustained tension.

These movements train the entire system, grip, shoulders, trunk and hips, in one go. That is efficiency and effectiveness combined.

No mirror muscles. No gimmicks.

Core Strength and Injury Prevention

A strong, stable core reduces injury risk because it allows force to be transferred efficiently. When the core fails, stress gets dumped into the lower back, hips and knees.

Many common injuries are not caused by weak legs or arms, but by poor trunk control under fatigue. Training the core as a stabiliser, not a mover, addresses this directly.

This becomes more important as training intensity increases or as people age. Stability protects longevity.

Why Aesthetic Abs Don’t Equal Strength

Visible abs are largely a product of low body fat. They say very little about how well your core functions.

Some of the strongest cores belong to people who never train abs directly. Their strength is earned through load, movement and repetition, not isolation.

If your core training leaves you flat on your back staring at the ceiling, you’re probably missing the point.

How Force Training Does It Differently

Force Fitness training is built around movement under load. Our equipment exists to challenge posture, stability and force transfer in a way that reflects real demands.

Weighted movement teaches the core to brace automatically. No counting reps. No chasing a pump. Just work.

This is the kind of core strength that shows up when you need it.

The Bottom Line

The core is not a show muscle. It is a stabilising system.

If your training only teaches it to flex, you are underpreparing your body for real stress. Train the core to resist movement, stabilise load and function under fatigue.

Stop chasing abs. Start building a core that actually works.
