=== Abdominals === The [[Rectus abdominis muscle|rectus abdominis]] and [[Transversus abdominis muscle|transversus abdominis]] contract continually while performing push-ups to hold the body off the floor and keep the legs and [[torso]] aligned. The rectus abdominis spans the front of the abdomen and is the most prominent of the abdominal muscles. The transversus abdominis lies deep within the abdomen, wrapping around the entire abdominal area. Both muscles compress the abdomen, and the rectus abdominis also flexes the spine forward, although it does not execute this function when performing push-ups.
