@dustydoesmobility: Turning to grab something from the back seat should not feel like a maneuver, but a trunk that only ever faces a screen loses the strength to rotate under control. Alternating Dumbbell Core Rotation kneels tall with a dumbbell held out at arm's length and swings it slowly side to side, so the obliques and deep core drive the turn while the hips stay square and the shoulders stay packed. 8 to 10 each side.
