Core muscles are a group of muscles located in the abdomen, lower back, and pelvis. They include the rectus abdominis, obliques, transverse abdominis, and erector spinae. These muscles work together to stabilize the spine and pelvis, support posture, and enable movement in various activities. Strengthening core muscles is essential for overall fitness and injury prevention. A strong core helps improve balance and stability, making everyday tasks easier. It also plays a crucial role in athletic performance, as many sports require a strong and stable core for effective movement and power generation.
