A traditional plank is generally on your forearms, but moving into a high-plank position on your hands will challenge your muscles in a slightly different way. As for the position of your head, it may be tempting to look down at your feet while planking, but this will throw off the line of your body. Therefore, it’s best to train your eyes on the floor directly between your hands to stay strong and steady, even as holding your plank becomes more difficult.
