A sit-up is a special way to train your tummy muscles.

This exercise helps to strengthen and tighten your abdominal muscles. It is a way to build muscle endurance. Some people call this a core exercise. It is similar to a move called a curl-up. However, a sit-up uses a fuller range of motion. This means it works even more muscles in your body.

There is a specific way to perform a sit-up. First, you lie down with your back on the floor. You should bend your knees and your toes. This helps to reduce stress on your spine. Next, you place your hands behind your head. You can also cross your arms over your chest. You lift your upper and lower vertebrae off the floor. You stop when everything above your buttocks is not touching the ground.

People have found many ways to change this move. You can make the exercise easier for yourself. Try placing your arms further down away from your head. You might place your palms on your shoulders instead. To make it harder, you can try weighted sit-ups. Some people use an incline sit-up on a slant. An incline sit-up with arms behind the neck is also very intense.

Some groups have changed how they train their bodies. In 2015, a big change happened in the U.S. armed forces. Every branch of the military began to phase out sit-ups. They also began to phase out crunches. They did this because of high rates of lower-back injury. Now, these groups use a move called a plank instead. This change helps to keep their backs safe from harm.

It is important to use the right form. Doing sit-ups the wrong way can cause back pain. It can also cause your lower back to arch. This increases the risk of a back injury. Some people think sit-ups can cause spot reduction of fat. This is not true. You cannot lose fat in just one spot. To get a "six pack," you need muscle growth and fat loss. This fat loss must happen across your whole body.
