The bird dog works core strength and back stability on all fours.
On all fours, hands under shoulders and knees under hips, flat back.
Simultaneously extend one arm in front of you and the opposite leg behind you, until aligned with the back. Hold for a second, return, then switch sides.
The pelvis stays parallel to the floor: do not rotate your hip to lift the leg higher.
