Core exercise is any exercise that works any part of your trunk to your pelvic region. When most people tell me they want to work on their core, this means they want to work on their abdominal muscles. The abs aren't the only part of your core as so is your back and spine.
The best core exercises may surprise you. It's not enough to just do ab crunches and sit ups. To build a strong core you need to exercise a variety of muscles, from your hips to your shoulders. Most people think of the core as a nice six-pack, or strong, toned abs, but the truth is that the abdominal muscles are a very small part of the core.
