In other fitness pursuits, you may have learned to go through the motions first and perfect your form second. In Pilates, it's the other way around. You learn to control your abs first and then proceed through a series of more progressive movements. At all times, you should feel in control of your body.
I don't believe in strict diets or starving yourself; eat three meals a day. I believe in eating a good breakfast, a good lunch and a light dinner. Eat breakfast like a king, eat lunch like a queen, and eat dinner like a pauper. Your ultimate goal is to eat all the basic food groups in those three different meals.
