kõhulihased

Kõhulihased, commonly referred to as abs, are a group of muscles located in the anterior abdominal wall. Their primary functions include supporting the spine, facilitating trunk movement such as bending and twisting, and aiding in respiration. The main abdominal muscles are the rectus abdominis, external obliques, internal obliques, and transversus abdominis.

The rectus abdominis is the superficial muscle that runs vertically along the front of the abdomen, often visible as "six-pack" abs when body fat is low. The external and internal obliques are located on the sides of the torso, with the external obliques lying on top of the internal obliques. They are responsible for rotational and lateral bending movements. The transversus abdominis is the deepest abdominal muscle, acting like a natural corset to stabilize the core.

Strong abdominal muscles are crucial for maintaining good posture and preventing lower back pain. They play a vital role in almost all physical activities, from lifting and carrying to athletic performance. Exercises like crunches, planks, leg raises, and Russian twists are commonly used to strengthen and develop these muscles. A balanced diet and cardiovascular exercise are also important for reducing body fat to reveal the abdominal muscles.
