What are the exercises for abdominal muscles?

I believe that every boy hopes to have eight-pack abdominal muscles, and in many fitness exercises, many people also regard abdominal muscle training as a fitness project, but many people have only a vague understanding of how to train abdominal muscles. Some people even have not developed abdominal muscles after training for a long time. In fact, in most cases, it is because the movements are not standard enough. So, what are some exercises to train your abdominal muscles?

First, what are the exercises to train the abdominal muscles? Aerial boarding: Lie on your back on the floor with your lower back close to the ground. Place your hands beside your head and arms open. Lift your legs and slowly move like a bicycle. Exhale, lift your upper body, touch your left knee with your right elbow, hold the position for 2 seconds, and then return to the original position. Then touch your left elbow to your right knee, hold for 2 seconds, and then slowly return to the starting position. Fitness ball crunch: Lie flat on a fitness ball with your feet flat on the ground, your hands on the sides of your head, and your arms outstretched. Slightly pull your chin toward your chest, exhale, contract your abdominal muscles and lift your upper body about 45 degrees, hold for 2 seconds, then slowly return to the starting position. To maintain balance, you can spread your feet further apart. To increase the difficulty, do it with your feet together.

Second, leg raise and crunch: Lie on your back on the floor with your lower back pressed against the ground. Place your hands beside your head and arms open. Lift your legs to 90 degrees with your upper body, cross your legs, and bend your knees slightly. Exhale, contract your abdominal muscles, lift your upper body, and keep your lower back off the ground. Hold for 2 seconds, then slowly return to the starting position. Be careful to keep your chin slightly tucked toward your chest. Reverse crunch: Lie on your back on the floor with your lower back pressed against the ground, your hands on both sides of your body, your legs raised to 90 degrees with your upper body, your legs crossed, and your knees slightly bent. Tighten your abdominal muscles, then exhale and slightly lift your hips and lower back off the ground, hold for 2 seconds, then slowly return to the starting position.

Lay your legs flat on the ground with your knees bent. Slightly pull your chin toward your chest, contract your abdominal muscles, exhale and lift your upper body, but your lower back should not leave the ground.

Your hands rest on either side of your head, without locking your fingers. Slowly lift your body up while you contract your abdomen. Squeeze your elbows up and bring your thighs to the sides. At the top of the movement, flex your abs for one count and then slowly lower your body back to the starting position. Be sure to maintain at least two inches of space between your back and the bench at the bottom of the movement. Additionally, for increased muscle building, hold a weight plate over your chest for added resistance.
