Abdominal exercises, also known as “abs exercises,” are exercises that target the muscles of the abdomen, including the rectus abdominis (the “six-pack muscle”), the transverse abdominis (the deepest abdominal muscle), and the obliques (the muscles on the sides of the abdomen). These exercises are designed to strengthen and tone the muscles in the abdomen, improve core stability, and may help to reduce the appearance of belly fat. Examples of abdominal exercises include crunches, leg raises, planks, Russian twists, bicycle crunches, and many more.
