Crunches tone abdominal muscles and can lead to a six-pack with a healthy diet and exercise. Basic and reverse crunches can be done on a mat or with equipment, and proper breathing is important. The number of sit-ups depends on the individual’s activity level.
Crunches are exercises that work to tone the abdominal muscles around the stomach and abdomen. Although many people may find abs monotonous, when combined with time, patience, exercise, and a healthy diet, they will eventually see good results. For those who work hard on their diet and exercise, doing crunches can help them see toned abdominal muscles, known as a six-pack. Crunches are different from crunches in that they use the abdominal muscles instead of the psoas muscles next to the spine.
There are several forms of mat-based crunches. The most basic and most common is the traditional crunch. Just lie on your back on a mat, bend your knees, and cross your hands over your chest. Next, lift your chest off the mat using your abdominal muscles, while keeping your lower back pressed into the mat. Some people only lift their chest a little difference and some people lift their upper body quite a bit; It is better not to reach the knees to avoid injury.
Reverse crunches are also very popular. With the reverse crunch, the legs are lifted, the arms are brought alongside the body, and the hips are slowly lifted off the mat. Reverse crunches work the lower abdominal muscles.
Some people prefer to use equipment when strengthening and toning their abdominal muscles. Crunches can be achieved with a stability ball if a person likes a little more cushioning under their back. A stability ball is a large ball made of rubber. To do a crunch on a stability ball, a person can rest their back on the ball, cross their hands over their chest, and then lift their chest off the ball.
Some athletic centers have equipment that simulates the crunch movement without using a mat or stability ball. There are specific abdominal machines that force the user to contract their stomach muscles to lift a series of weights. Also, there are incline benches that are for someone who wants to hang upside down, hold a weight, and then crunch their torso up.
Using proper breathing techniques is one of the most important considerations for those doing crunches. In general, breathe out as you go up and inhale as you go down. Using good breathing techniques will prevent people from tensing their muscles and also oxygenate those same muscles.
The number of sit-ups that must be completed depends on the individual’s activity level. For example, someone new to exercise or abs may start out by doing just 20 sit-ups a day. He can increase that number as his muscles get stronger. Eventually, a dedicated abs person can do several hundred each day.
