# Dead Bug Anti-extension drill — the limbs move while the trunk stays perfectly still. - **Category:** Warm-up - **Type:** Anti-extension - **Targets:** Deep core (transverse abdominis), hip flexor control - **Prescription:** 8 per side, slow and controlled - **Defaults:** 3 × 8 bodyweight ## Setup Lie on your back. Arms straight up over the shoulders, hips and knees bent to 90°, lower back pressed into the floor. ## Execution 1. Brace and exhale as you lower one arm overhead and the *opposite* leg toward the floor. 2. Stop just before the lower back peels off the floor. 3. Return under control and switch sides. ## Cues - Lower back glued to the floor the entire time — that contact *is* the exercise. - Slow negatives; the reach out should take 2–3 seconds. - Ribs down, no flaring as the arm goes overhead. ## Common Mistakes - Arching the lower back as the leg lowers. - Moving arm and leg on the same side. - Rushing reps and turning it into a flutter kick. ## Progression Heels sliding on floor → bent-knee reach → straight-leg reach → both legs lowering together → light weight held overhead
