I wonder if you are holding your breath while you perform this ‘plank’ exercise? If you do not continue to breathe normally whilst exercising, it could result in dizziness (due to a reduction in oxygen and a drop in the blood pressure). The actual exercise is used to strengthen the abdominal muscles and the ‘core’ muscles.
If breathing deeply and properly does not help, then I would suggest you do not continue with this exercise, especially if it makes you feel unwell. There are other exercises you can do instead of this one to strengthen these particular muscles.
