I sincerely doubt it! I have been attending a yoga class for almost one year and I am still struggling to get the hang of it. I don't think an online tutorial will be able to help you find what you are looking for. Yoga is a specialized art form and it has to be learnt in the presence of a true master. I doubt that you will learn anything substantial with the help of an online class. Besides it is easy to fake online classes so you might be getting a raw deal. I suggest you opt for a proper class.
