How to build a better core
Your core is more than just your abdominals — it also involves your hips, back, and even your shoulders. To strengthen your entire core, take a loaded carry walk.
Your core is the stable part of your body that helps make everyday movements more efficient and safe — like whenever you reach, carry, walk, bend, or twist. A strong core offers other health benefits as you age in addition to proper movement (see "Get more from your core").
Some floor exercises like the plank and superman poses are great for engaging your core muscles. A plank pose is where you hold a push-up position — with straight arms or resting on your forearms — for 10 to 30 seconds.
