Dead bug
Also called Dead bugs
Dead bug is a core exercise done on your back, where you lower opposite arm and leg while keeping your trunk still. It is not a classical pilates exercise, but it is common in pilates-based and mat classes because it trains the same kind of control. Form matters because the whole point is to keep your lower back steady while your limbs move.
How to do Dead bug
- 1Lie on your back with your knees in tabletop and your arms reaching straight up toward the ceiling.
- 2Gently draw your ribs down and let your lower back rest close to the mat.
- 3Exhale and slowly extend your right arm overhead and your left leg forward, hovering both just off the mat.
- 4Lower only as far as your lower back stays steady.
- 5Inhale and bring the arm and leg back to the starting position.
- 6Repeat with your left arm and right leg.
- 7Continue for six to ten slow reps on each side.
Common mistakes and how to fix them
The lower back arches off the mat as the leg lowers.
Shorten the range, keep a bend in the knee as the leg lowers, and exhale fully to draw your ribs down.
The ribs flare up as the arm reaches overhead.
Reach the arm only as far as your ribs stay soft and down.
The movement is rushed.
Take a full breath for each rep and pause briefly at the starting position.
The arm and leg on the same side move together.
Pair opposite limbs, right arm with left leg, and slow down to keep the pattern clear.
Modifications
- Move only the legs and keep both arms reaching up.
- Tap your heel to the floor with a bent knee instead of extending the leg.
- Move only the arms while your legs stay in tabletop.
Benefits
- Builds deep core strength and control.
- Trains a steady trunk while the limbs move.
- Improves coordination of opposite arm and leg.
- Offers a core option that keeps the head and neck resting.
Breath
Exhale as you extend the arm and leg, and inhale as you bring them back. A long exhale helps keep your ribs down.
Take care
Take care with lower back or shoulder injuries, and keep the range small if your back starts to lift. Stop if you feel sharp pain.
Dead bug questions
Is dead bug a pilates exercise?
Dead bug is not part of the classical pilates repertoire, but it is common in pilates-based and mat classes. It trains the same idea of a steady center while the limbs move.
Why does my back arch during dead bug?
Your leg is likely lowering farther than your core can control. Bend the knee more, shorten the range, and exhale fully as you reach.
How many dead bugs should I do?
Start with six to ten slow reps on each side. Add reps only when your lower back stays steady the whole time.
