Planking is the kind of exercise that makes your muscles expand and stretch. It stretches out all of your core muscles all over your body such as shoulders, shoulder blades, collarbone, hamstrings, feet, etc. By doing some side planks you can also stretch your oblique muscles. So when it comes to hyperextending your toes, side planking will really benefit you as it is crucial to support your body weight.
