Core Strength Fitness Classes

Core strength is integral to movement and stability, both in and out of the gym. Your core is involved in everyday activities, from carrying groceries to keeping you upright, as well as supporting all the movements you do in your workouts. Core workouts can help you improve your core stability, to improve your balance, posture and functional movement.

More about Core Strength

What does core strength involve?

Despite what you’ve probably been led to believe, core strength is about so much more than building a six-pack of abs. Your core includes your abdominal muscles, and also a bunch of muscles in your back and around your pelvis, including your obliques, back- and spine-supporting muscles, and pelvis-stabilising muscles.

Why is it important?

Improving your core strength will allow these muscles to become stronger and more stable, to allow better movement throughout your body, support your spine, improve your balance and posture, and help prevent falls or injuries.

Fitness First is all about helping you strengthen key muscle groups, like your core, so we’ve developed a range of core strengthening classes to help. Building core stability is another step on your journey to improving your fitness and function!
