Core training is one of the most talked-about areas in the gym. It is also one of the most misunderstood.
For many, it starts and ends with chasing a six-pack. Endless crunches, quick burn workouts, and the feeling that if your abs are not on fire, you have not done it properly.
That is not how we approach it at Foundry.
Core training is not about doing more. It is about doing the right things, consistently, and with purpose. Get it right, and everything else in your training improves.
Core Training Is More Than Abs
Let’s clear this up early.
Your core is not just your abs.
It is everything from your shoulders down to your hips working together to stabilise and control movement. That includes your abdominals, obliques, lower back, and your glutes.
The job of the core is simple:
- Maintain posture
- Transfer force
- Stabilise your body under load
Whether you are squatting, running, lifting, or just getting through a long day at your desk, your core is involved.
At Foundry, we are not interested in isolating muscles for their own sake. We are focused on building a body that moves well, performs well, and remains resilient over the long term.
Core Training Matters In The Gym
A strong core does not just look good. It underpins everything you do.
If your core is not doing its job, you will feel it:
- Your squat lacks stability
- Your deadlift breaks down under load
- Your pressing feels disconnected
- Your posture starts to slip
When your core is working properly, the difference is clear:
- Better control under load
- More efficient force transfer
- Reduced strain on joints
- More consistent training progress
Your core is the link between your upper and lower body. Strengthen that link, and everything improves.
The Big Three Core Functions To Master
Before you look for variety, you need to master the fundamentals.
At Foundry, we focus on three key core functions.
1. Anti Extension
This is your ability to resist excessive arching through the lower back.
It is essential for protecting your spine, particularly during heavy lifts.
Think ribs down, pelvis controlled, and no unnecessary movement.
Exercises that build this:
- Plank variations
- Dead bugs
- Ab rollouts
These are about control, not duration.
2. Anti Rotation
This is your ability to resist unwanted twisting through the torso.
It plays a huge role in maintaining stability as your limbs move.
Exercises that build this:
- Pallof press
- Bird dogs
- Shoulder taps
This is what keeps you stable when everything else is moving.
3. Flexion
Flexion has been misunderstood and often avoided.
The reality is simple. It still has a place when used correctly.
Flexion allows you to control movement through the spine when needed.
Exercises that build this:
- Reverse crunches
- Hanging knee raises
- Sit-up variations
Focus on controlled movement. Avoid momentum.
Build The Foundation First
There is always a temptation to jump into advanced exercises.
That is usually where progress stalls.
Before anything else, build a foundation of:
- Control
- Stability
- Consistency
This is no different to how we approach nutrition. Start with simple, effective principles and build from there.
If the basics are not solid, adding complexity will not fix the problem.
Add More Dimensions To Your Training
Once you have built a solid base, you can expand your training.
Anti Lateral Flexion
This is your ability to resist side bending.
It becomes important when dealing with uneven loads.
Exercises that build this:
- Side planks
- Suitcase carries
Dynamic and Reactive Stability
This is where core training becomes more athletic.
You are now controlling movement under load rather than just holding a position.
Exercises that build this:
- Turkish get-ups
- Contralateral split squats
- Loaded carries
These movements better challenge your body.
Core Training Mistakes
Effort is not usually the problem. Direction is.
Here are the most common mistakes:
- Only training the abs
- Chasing fatigue instead of control
- High reps with poor technique
- No clear progression
- Treating core as an afterthought
Core training should be structured, not random.
Program Your Core Properly
You do not need endless exercises to build a strong core.
You need consistency and intent.
Frequency:
Train your core 2 to 4 times per week.
Placement:
- Early in the session for activation
- Integrated into your main lifts
- As targeted accessory work
Structure:
Keep it simple:
- Choose 1 to 2 exercises per session
- Focus on one stability-based movement
- Pair it with one dynamic or loaded movement
Quality over quantity, every time.
Make It Work For You
Your training should reflect your goals, your experience, and your lifestyle.
There is no perfect routine.
The best approach is the one you can apply consistently and progress with over time. That principle runs through everything we do. The best plan is always one you can stick to
Core Training and Performance
Core training is not a standalone piece of your programme.
It supports everything:
- Strength training
- Running and conditioning
- Posture and daily movement
- Injury resilience
A strong core allows you to move better, lift better, and recover better.

If there is one takeaway from this, it is simple.
Train your core with purpose.
Not for the burn. Not to tick a box. Not as an afterthought at the end of your session.
Train it to support everything else you do.
Our approach is built around what actually drives results. That means focusing on movement quality, strength, and progression that lasts. Core training is not treated as an extra. It is built into the way you train from day one.
Across our personal training gyms, you will not find random circuits or endless crunches. You will find structured programmes, coached sessions, and a clear progression path tailored to your level.
Get the basics right. Apply them consistently. Progress with intent.
That is how we do things at Foundry.
