Bird Dog Plank!
Begin in a plank on your hands and toes. Keeping your torso stable, lift your right hand and left foot about six inches off the floor. Without rocking your torso, lower your right hand and left foot and immediately lift your left hand and right foot. Repeat until 10 reps total are complete. The key is not how high you’re able to lift your hand and foot, but maintaining proper alignment and form when transferring from side to side.
*Consult your physician before performing exercise.
