Yup, your body adjusts to the exercise you do. As a D person, it took me a long time to work up to the number of situps I can do without having to 'go'. Now I can do as much as I want. Running is still very hard for me to do without getting an attack becuase I don't go very often. If you constantly change the types of exercise you do, your stomach muscles wouldn't have the chance to get as accustomed to it.
