Common Dead Bug mistakes
Arching lower back excessively which can cause injury.
A compromised back position during the Dead Bug puts your spine under unnecessary shear force. Brace your core and maintain a neutral spine throughout the movement.
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.
Holding your breath incorrectly during the Dead Bug spikes your blood pressure and reduces core stability. Inhale during the eccentric (lowering) phase and exhale during the concentric (lifting) phase.

All levels, especially those with back issues.
How to Program the Dead Bug
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.
