Plank: Start on your hands and knees and come up into a push-up plank position, balancing on hands (or elbows) and toes (or knees). Align wrists under shoulders; keep your back straight and the abs and glutes tight (to keep the back from sagging). Hold the position and breathe out for 10 seconds, exhaling to tighten the abs and draw the navel to the spine.
“First and foremost you have to train your abs on all three planes. You have to train them forward and back with something like a crunch or double crunch. You have to train your abs laterally to hit the obliques with something like a dumbbell side bend. And you have to train your abs on a rotational plane—your transverse abs—and you can do that from a seated trunk twist."
