Exercise guidance based on established strength-training principles and practical programming.
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
All levels, especially those with back issues.
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.

We slot it into the right day with sets, reps, and progression you can follow.
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.
Use dead bugs for warm-up, core training, or back rehabilitation. Program 3 sets of 10-12 reps per side. Progress by extending limbs further toward the floor as core strength improves.
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.
All levels, especially those with back issues.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 10-12 each side. Rest 30 seconds.
