Planks are an isometric core exercise where you hold your body in a straight line, supported on your forearms or hands and your toes. They build deep core stability, working the transverse abdominis, rectus abdominis, and obliques, along with the shoulders, glutes, and back as stabilizers. Set your elbows under your shoulders, extend your legs behind you, and hold your body rigid from head to heels without letting your hips sag or pike. Brace your core as if bracing for a light punch, squeeze your glutes, and keep your neck neutral by gazing at the floor. Breathe steadily rather than holding your breath. Hold for time, stopping when your form starts to break rather than pushing into a sagging position. Planks teach your core to resist movement and stabilize the spine, a foundation that supports nearly every lift and athletic action.
