Every bride wants fabulous, flat abs under her gown, especially if it fits tightly around the midsection. Planks are a great way to tone your upper abs without breaking much of a sweat. This move works your innermost ab muscles, called the transverse abdominus, which are the muscles responsible for creating the appearance of a flat stomach.
Start in a push-up position, creating a diagonal line with your body from your toes to your head. Put your hands directly under your shoulders and keep your feet together. Hold this position for as long as you can, making sure you're engaging your abdominal muscles to hold yourself up. You'll feel the burn if you hold this pose long enough! For a more difficult version, do the plank pose with your forearms resting on the floor, creating a straight line with your body instead of a diagonal line.
