This page is not medical advice or a rehabilitation protocol. Ely's personal review applies to purchased workout plans and does not replace an in-person assessment by a licensed healthcare professional.
The dead bug teaches core stability by challenging your ability to maintain a flat lower back while moving your limbs. This anti-extension exercise targets the deep core muscles that protect your spine during movement.
When to use it
Use for core stability and back health.
Who it's for
Adults using the movement for general fitness who can perform it without pain. Clinical concerns require guidance from a licensed healthcare professional.
Press your lower back firmly into the floor and maintain this contact throughout. If your back arches as you extend your limbs, reduce your range of motion until core strength improves.

Lie on back with arms extended toward ceiling.
Lift legs with knees bent at 90 degrees.
Press lower back into floor.
Extend opposite arm and leg toward floor.
Return to starting position.
Repeat with other arm and leg.
Keep lower back pressed into floor.
Breathe out as you extend limbs.
Great for core stability.
For general fitness, start Dead Bug with 1-2 light, controlled sets and increase only when the movement remains comfortable. This is not rehabilitation dosage; use the frequency and progression given by your licensed healthcare professional for an injury or surgery.
Arching lower back excessively which can cause injury.
Changing your back position during the Dead Bug can alter the movement and make the load harder to control. Brace your midsection and keep the torso position called for by the exercise.
Moving too quickly which reduces time under tension.
Isometric holds like the Dead Bug build strength at specific joint angles. This mistake changes the angle and reduces how hard your Rectus abdominis has to work. Lock into position and hold it.
Holding breath, which reduces blood flow and can cause dizziness.
Inconsistent breathing during the Dead Bug can make it harder to maintain a steady brace. Use a repeatable breath pattern that matches the exercise and avoid extending a breath hold beyond what you can control.

These ranges illustrate ways to organize training. They are not an individual prescription. Adjust them for the exercise, your experience, and the rest of your program.
Heavier loads can be useful for developing maximum strength. The range shown is an example, and the load must match your current technique and capacity.
Muscle growth can occur across different loads and repetition ranges. This example is not a uniquely effective zone; your overall program and effort also matter.
This is an example of a longer set. A repetition target alone does not establish joint safety or whether the exercise is appropriate for you.
Example: For general fitness, start Dead Bug with 1-2 light, controlled sets and increase only when the movement remains comfortable. This is not rehabilitation dosage; use the frequency and progression given by your licensed healthcare professional for an injury or surgery.
Background for resistance exercises: the 2026 ACSM position stand covers healthy adults, and a load-comparison review found similar muscle growth across loads in studies using sets taken to muscular failure. These findings do not validate every exercise-specific range shown here or require training to failure.
This is one example of how Dead Bug could sit inside a complete workout. Your plan may use different movements after Ely checks your assessment.
