Can sit-ups help you lose belly fat? Why?

For people who sit in the office for a long time, they will unknowingly gain a circle of fat on their stomach, which is not very beautiful and makes them look bloated. So how can they lose the fat on their stomach? Is doing sit-ups useful? What is the difference between sit-ups and sit-ups?

What is the difference between sit-ups and crunches?

Sit-ups and crunches The biggest difference between crunches and sit-ups is whether the hip joint is fixed. Other than that, the first step of sit-ups is the same as that of sit-ups. It can be understood that sit-ups include crunches, and it is not wrong to call crunches half-way sit-ups.

Abdominal crunches are better than sit-ups

Many people think that sit-ups must be performed with elbows touching knees. In fact, this posture mostly relies on the back lats to pull the arms to provide inertia, and the abdominal muscles will reduce their strength. This kind of leverage is more common when you are tired at the end. In order to pursue speed, some people will quickly bounce up when they fall down, thus omitting the abdominal muscles from working, and the sit-up becomes an exercise that only moves the hip joint.

In addition, some people's waist cannot be close to the ground due to the anterior tilt of the pelvis. After the abdominal muscles are activated, the fulcrum jumps directly from the thoracic spine to the sacrum. Without the lumbar spine as a fulcrum, the effect of sit-ups on abdominal muscle training is greatly reduced.

2 basic training methods for crunches

Half crunch

Effect: Develop eight-pack abs.

Action: Bend your knees to 90 degrees, with your feet flat on the ground. Place your hands on your ears and use your abdominal strength to slightly roll up your upper body (no more than 45 degrees). Keep your waist close to the ground, lift your shoulders off the ground, and roll up your abdomen. You can clearly feel the abdominal muscles being squeezed. After bending your upper body to the limit, pause for a few seconds and return to a flat position. Repeat the exercise.

Full abdominal crunch

Effect: slim waist and reduce belly.

Action: Lie flat on the bed or bench with your feet on the ground, and your calves at a 90-degree angle to your upper body. Place your hands on your ears and use your abdominal muscles to slowly roll up your upper body until your abdominal muscles are fully tightened, bringing your elbows as close to your pelvis as possible. Keep your legs relaxed during the entire process, and do not lift your legs when rolling up your upper body. Hold for a few seconds and then return to lying flat, repeating the exercise.
