There is a lot of common sense in this video and it's made by someone who needs to look good to earn her living.
Learning tips and taking advise from someone who has a professional interest in the subject is always a good idea. Remember though, this lady is a professional model, what works for her may not be right for you or your life style.
But, as we have mentioned before, researching a subject from every possible angle helps build your own personal knowledge, which will help you make informed decisions and hopefully this will lead to a positive weight loss experience. We would strongly suggest that you make your own file containing the video's, articles and routines that you think could work for you, then mould this file into your weight loss program. Be patient when preparing this program, if you rush you will make bad choices and as a result affect your success percentage. Remember this simple rule:
"Failing to prepare is preparing to fail"..... good luck.
