Advanced Core Series: The Plank
Looking to level up your core strength? We’re kicking off a new series with one of the most effective foundational exercises: the plank.
A well-performed plank builds strength where it matters most, helping your posture, protecting your spine, improving sporting performance, and supporting everything from lifting weights to carrying groceries.
Muscles Used:
Transversus abdominis (TA): the deepest abdominal muscle acting like a “corset” to stabilise and support the spine and internal organs.
Re**us abdominis: the six-pack muscle helping to maintain trunk control.
Obliques: assist with rotational stability and side-to-side control.
Glutes: keep your hips aligned and stable.
Shoulder stabilisers: support your upper body and prevent sagging through the shoulders.
Why These Muscles Matter:
Developing a strong core is about building a stable, resilient base for your whole body. It is has a number of benefits including:
- Better posture
- Reduced lower back pain
- Improved balance and control
- Safer lifting mechanics
- Improved sport performance
How to Plank:
Start on your forearms, elbows under shoulders.
Step your feet back and create a straight line from head to heels.
Engage your core, pulling your belly button towards your spine.
Press the floor away so your shoulder blades stay wide.
Hold this position, focusing on good form.
Goal: Hold for 60-seconds with good form before progressing.
Progressions:
1. Feet on a ball: Adds instability, demanding more from deep core + shoulder stabilisers.
2. Add a leg lift: Increases glute activation + anti-rotation control.
3. Upper body on a BOSU + feet on a ball: Combined challenge.
