Is it better to run with a slim belly or sit up

The choice between running or sit ups for slimming the belly depends on individual physique and goals. Running is more suitable for overall weight loss, while sit ups are more targeted at strengthening abdominal muscles. Running is an aerobic exercise that can effectively burn body fat, including abdominal fat accumulation. By jogging or running intermittently for more than 30 minutes, one can improve cardiovascular function, accelerate metabolism, and help reduce visceral fat. During running, the core muscle group naturally participates in maintaining body balance and has an indirect effect on shaping abdominal lines. But it is important to maintain the correct running posture and avoid compensatory force from the lumbar spine.

Sit ups are a typical anaerobic strength training that primarily stimulates the rectus abdominis and external oblique muscles, regenerating muscle fibers through tearing to make the abdomen firmer. For people with low body fat percentage, sit ups can quickly reveal the vest line. However, relying solely on sit ups cannot eliminate deep fat, and excessive training may lead to strain on the cervical or lumbar spine. It is recommended to perform a variety of exercises such as abdominal rolling and plank support.

It is recommended to combine running with sit ups for training, and schedule 3-4 30 minute runs per week with 2 specialized abdominal exercises. Control the intake of refined carbohydrates in diet, increase high-quality protein and dietary fiber, and avoid high sugar and high-fat foods. Lack of sleep can hinder fat metabolism, so it is necessary to ensure at least 7 hours of high-quality sleep. When the body fat percentage exceeds the standard, aerobic exercise should be prioritized, and regular monitoring of data changes should be carried out in conjunction with a body fat scale.
