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.
Start out slowly when you work the abs. Aim for 10 to 15 reps for each exercise. Examples of exercises to add to your core workout routine include reverse crunches, planks, pelvic lifts, pelvic tilts and trunk twists. You can perform these exercises at home and do not require you to purchase any fitness equipment.
