It is Simple.
You want to lose weight: follow the slow carb eating method (purposefully not using the word "diet") which is described in the 4-Hour-Body book. As suggested in the book, if you are not interested in anything else, simple read the 150 pages about slow carbs. I lost 27 pounds since May 20th of this year, without being hungry. WITHOUT BEING HUNGRY!!!! Also once a week you can eat whatever you want.
You want to improve your rowing technique: Work with me, send in your rowing footage and a day later you receive the most comprehensive analysis of your rowing stroke you have ever gotten. I point out what is good and not so good. You will be delighted to get a list of clearly explained exercises which easily correct technical deficiencies and improve your stroke.
