How to Do a Dead Bug
The dead bug has you lie on your back and slowly extend opposite arm and leg while keeping your lower back pressed to the floor. It teaches deep core control without straining the spine, making it one of the safest and most useful core exercises for beginners.
The dead bug looks gentle, but it teaches a skill Many people lack: keeping the spine still while the arms and legs move. That control is what protects your back during real lifts, and it is why we use dead bugs so often with beginners.
You only need floor space, so it fits any bedroom or our Putra Heights centre. It is back-friendly and low-risk, so it suits people easing into training or rebuilding core control after time off.
What it trains and who it suits
It trains the deep core to keep the lower back flat while the limbs move. It suits beginners, people with back concerns cleared to train, and anyone wanting better control for heavier lifts.
Because you are on your back with support, there is minimal spinal load, making it a safe way to build genuine core strength.
Step-by-step cues
- Lie on your back, arms up and knees bent over the hips
- Press your lower back flat into the floor
- Slowly lower one arm and the opposite leg toward the floor
- Stop before your back arches off the ground
- Return and repeat with the other arm and leg
Common mistakes and quick fixes
- Lower back arching up, press it down and shorten the range
- Moving too fast, go slowly to keep control
- Holding the breath, exhale as you extend the limbs
- Same-side arm and leg, always use opposite arm and leg
Regressions, progressions and when to stop
Too hard? Move only the legs or only the arms at first. Too easy? Slow it further, add light weights, or hold at the end range. At home the floor is enough; at our centre we add resistance and tempo for more challenge.
- Stop if you feel sharp low-back pain rather than core effort
- See a professional if your back keeps arching no matter how slow you go
