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, providing support for everyday movements and activities. Strengthening core muscles is important for overall fitness and injury prevention. A strong core improves balance, posture, and athletic performance. It also helps in activities like lifting, twisting, and bending, making daily tasks easier and safer. Regular exercises, such as planks and crunches, can enhance core strength effectively.
