Sit-up form. The sit-up is an abdominal endurance training exercise to strengthen, tighten and tone the abdominal muscles.It is similar to a curl-up (that target the rectus abdominis and also work the external and internal obliques), but sit-ups have a fuller range of motion and condition additional muscles.
Starting out by lifting lower weights to build endurance in the lower back as well as the upper pulling muscles. Upper back muscles often have a lot of slow-twitch fibers so bent-over rows can respond better than some exercises that use muscles with a higher ratio of fast-twitch fibers. Doing the exercise with a slow tempo and avoiding jerking.
The Russian twist is a type of exercise that is used to work the abdomen muscles by performing a twisting motion on the abdomen. This exercise is performed sitting on the floor with knees bent like in a "sit-up" position with the back typically kept off the floor at an angle of 45°.
The Roman chair is also used to perform exercises for the abdomen. An exerciser lies supine with their hips supported on the rear (weight on the gluteus maximus) as they bend backward and lift themselves up with their rectus abdominis while stabilizing the pelvis with the hip flexors. If the pelvis moves during the exercise then the hip flexors ...
The linea alba is a white, fibrous band that is made of the bilateral rectus sheaths that join at the anterior midline of the body. These enclose the rectus abdominis muscles (a pair of long, linear muscles, commonly called the “sit-up” muscles) that originate at the pubic crest and pubic symphysis, and extend the length of the body’s trunk.

The leg raise is a strength training exercise which targets the iliopsoas (the anterior hip flexors).Because the abdominal muscles are used isometrically to stabilize the body during the motion, leg raises are also often used to strengthen the rectus abdominis muscle and the internal and external oblique muscles.
