5'6" over 300#

I am committed to losing weight. In the past I had a cheap knock off rower and got into pretty good shape with it until I broke it. I just purchased a Concept 2 Model D rower to go along with my 1 1/2 hours a day walking. Once I get some more weight off I hope to get back to slow jogging/speed walking.

I have to work full time, spend about 1 1/2 to 2 hours a day with the kids on their studies, and cook my own meals. I am still committed though. Lots of stir fries using loads and loads of veges with a little meat and currently no grain (plan to add whole grain back in once I lose more weight). No sauces and just a little oil used in cooking. Lots of spices.

My biggest problem is ability to concentrate at work as I try to lose weight.
