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.
Updated January 12, 2016. This core workout focuses on using an exercise ball to strengthen all of the muscles in the abs and back or, as we say in the biz, the 'core.' I love these moves because they not only strengthen the core, they target balance, stability and overall coordination, making this a multi-purpose workout.
