Abdominal exercises are physical activities designed to strengthen the muscles in the abdomen. These exercises target the rectus abdominis, obliques, and transverse abdominis, helping improve core stability and overall fitness. Common examples include crunches, planks, and bicycle crunches. Incorporating abdominal exercises into a workout routine can enhance posture, balance, and athletic performance. A strong core supports daily activities and reduces the risk of injury. It's important to perform these exercises with proper form to maximize benefits and minimize strain on the back and neck.
