# Bird Dog Anti-rotation drill — extend opposite limbs while the hips and spine refuse to twist. - **Category:** Warm-up and main circuit - **Type:** Anti-rotation - **Targets:** Spinal erectors, glutes, deep core, shoulder stability - **Prescription:** Warm-up 8 per side; main circuit 3 × 8–10 per side, slow ## Setup On all fours: hands under shoulders, knees under hips, spine neutral, gaze at the floor. ## Execution 1. Brace, then reach one arm forward and the *opposite* leg back until both are in line with the torso. 2. Pause for a beat at full extension — hips stay square to the floor. 3. Return under control and switch sides. ## Cues - Imagine a cup of water balanced on the lower back — nothing spills. - Reach *long*, not high: heel pushes back, knuckles push forward. - Slow, no momentum; the pause is where the work happens. ## Common Mistakes - Hips rotating open as the leg lifts. - Lifting the leg above hip height and arching the lower back. - Racing through reps. ## Progression Single limb only (arm *or* leg) → opposite arm + leg → paused 3-count hold → elbow-to-knee touch under the body between reps → hands on an unstable surface
