What does core strength actually mean and how to train it

When most people think of their core they think of fitness influencers with 6-pack abs. In reality, the core is much more than that. The core is a complex group of muscles that includes the abdominals, obliques, deep stabilizing muscles, muscles of the spine, diaphragm, pelvic floor, and even muscles around the hips.

What does your core actually do?

The muscles of your core all work together to stabilize the spine, transfer force between the upper and lower body, unload pressure from joints, and help us maintain balance and proper posture during movement.

The core acts as the foundation for nearly every movement in daily life. Whether you're carrying groceries, sitting in a chair, reaching overhead, standing, picking something up from the ground, or participating in sports, your core plays a critical role in your daily life.

Why should you train your core?

Your core works every day, but simply using it isn't the same as training it. While everyday activities keep the core active, they often don't challenge the muscles enough to maximize strength, and stability, or preserve muscle mass as we age. Targeted core training helps build a stronger foundation for movement, improving posture, balance, spinal support, and overall function. A well-trained core reduces stress on the back, enhances performance, and makes everyday activities feel easier.

How to train your core

Because the core includes many different muscles with unique functions, effective core training goes beyond crunches and sit-ups. The best programs include exercises that challenge stability, rotation, anti-rotation, bending, bracing, and posture to develop a strong, functional core that supports you in everyday life.
