Dead Bug
Dead Bug Exercise Description
The Dead Bug is a supine core-stability exercise that trains anti‑extension and anti‑rotation control while your arms and legs move. It primarily targets the anterior core—rectus abdominis, transverse abdominis, and internal/external obliques—by maintaining lumbopelvic stability against changing limb leverage. Performed with contralateral arm–leg reaches, it teaches dissociation of the limbs from a stable trunk and reinforces rib‑to‑pelvis alignment. Keeping a slight posterior pelvic tilt, ribs “down,” and consistent diaphragmatic breathing helps prevent lumbar extension and promotes a neutral, controlled spinal position throughout. This drill is widely used to build foundational trunk control that supports safe, efficient movement in daily tasks and compound lifts.

How To Do The Dead Bug Exercise
‘- Lie on your back; raise arms straight above shoulders, palms facing each other.
– Bring hips and knees to 90/90 (knees over hips, shins parallel to the floor).
– Lightly posteriorly tilt the pelvis to bring lower ribs down; maintain gentle low‑back contact with the floor.
– Brace the abdominal wall as if preparing for a cough; keep neck and jaw relaxed.
– Keep the head in line with the torso; eyes up.
– Inhale through the nose; on a soft exhale, slowly lower the right leg and left arm toward the floor.
– Stop the reach just before the low back wants to arch or ribs flare.
– Pause briefly; keep pelvis level and avoid trunk rotation.
– Return to the start under control, maintaining the brace.
– Switch sides and repeat with the opposite arm and leg.
– Throughout: move slowly, breathe steadily, keep shoulders relaxed, and prioritize control over range.
Dead Bug Tips
‘- Set up with arms straight above your shoulders, palms facing each other.
– Position hips and knees in a 90/90 angle so knees are over hips and shins are parallel to the floor.
– Lightly posteriorly tilt your pelvis to bring the lower ribs down and keep gentle low‑back contact with the floor.
– Brace your abdominal wall as if preparing for a cough while keeping your neck and jaw relaxed.
– Keep your head in line with your torso and your eyes looking up.
– Inhale through your nose, then on a soft exhale slowly lower the opposite arm and leg toward the floor.
– Stop the reach just before your low back starts to arch or your ribs begin to flare.
– Keep your pelvis level and avoid any trunk rotation during the movement.
– Return to the starting position under control while maintaining your brace.
– Throughout the exercise, move slowly, breathe steadily, keep your shoulders relaxed, and prioritize control over how far you reach.
Dead Bug Beginner Introduction
The Dead Bug is a ground-based core exercise performed while lying on your back with arms and legs lifted. It centers on keeping the middle of the body steady while the limbs move, challenging your ability to resist the low back from arching or the torso from twisting. Because the movement happens mainly at the hips and shoulders while the trunk stays quiet, it highlights control rather than big ranges of motion or heavy loading.
This drill places strong emphasis on the front of the core, including the abs and side abs, as they work together to steady the pelvis and spine against changing leverage from the arms and legs. Opposite arm-and-leg motion adds a coordination element, training the body to move the limbs independently of a stable center. Smooth, consistent breathing and a gently tucked pelvis support a more neutral back position. Over time, this pattern can help create a dependable foundation for everyday movements and larger compound lifts.
