Core-strength exercises strengthen your core muscles, including your abdominal muscles, back muscles and the muscles around the pelvis. Strong core muscles make it easier to do many physical activities. Core exercises improve your balance and stability.
Your core is the central part of your body. It includes your pelvis, lower back, hips and stomach. The stomach muscles sometimes are called abs. Core exercises train the muscles in your core to work in harmony. This leads to better balance and steadiness, also called stability. Stability is important whether you're on the playing field or doing regular activities. In fact, most sports and other physical activities depend on stable core muscles.
