Birddog
Kneel on the floor with your shoulders over your hands and your hips over your knees, shoelaces on the floor. First lift the abs away from the floor without moving your spine. Lift up out of your wrists.
Slide one leg straight, then lift it off the floor as high as you can without tilting your hips towards the floor, stopping at hip height. Hold for up to 10 seconds, then lower to starting position and repeat on other leg.
A mat is helpful
Rectus Abdominis, Biceps Femoris, Gluteus Medius, Pectoralis Major
TIP: This exercise is not for the impatient. Practice it every other day; first, in order to truly educate your TVA to engage without accessory muscles, and second, to keep the TVA strong.
