Your core equals your lower abdominals, your shoulder blade muscles, your lower back muscles and your hip mucles. They need to all work together to have a good core. Try this: Get on your back on the floor with your knees bent and feet flat on the floor. Roll your back flat and tighten your lower belly muscles to keep it flat. Keep it flat while you raise both bent knees and bring towards your chest. When you keep belly flat and back flat...this is a lot of work. The clam and bridge are other good core builders.
