trunkflexorer

Trunkflexorer is a term used to describe muscles that flex the trunk. These muscles are primarily located in the anterior (front) and lateral (side) aspects of the abdomen and thorax. The most prominent of these muscles is the rectus abdominis, often referred to as the "abs," which runs vertically along the front of the abdomen. Other significant trunk flexors include the internal and external obliques, located on the sides of the abdomen, which also contribute to trunk rotation. The transversus abdominis, the deepest abdominal muscle, plays a crucial role in stabilizing the core and assisting in flexion.

The primary function of the trunk flexor muscles is to bend the torso forward, bringing the chest towards the pelvis. This action is essential for numerous daily activities, such as sitting up from a lying position, bending over to pick up objects, and maintaining posture. They also play a vital role in stabilizing the spine during various movements and protecting the internal organs. Weakness or imbalance in these muscles can contribute to back pain and poor posture. Exercises that target the trunk flexors include crunches, leg raises, and planks. Proper training of these muscles is important for overall physical function and athletic performance.
