Why can't girls do sit ups

Girls can usually do sit ups, but caution is needed in some special circumstances. Sit ups may not be suitable for certain female groups due to excessive pressure on the lumbar spine, risk of pelvic floor muscle injury, and rectus abdominis muscle separation.

Sit ups exert significant pressure on the lumbar spine, especially when the movements are not standardized, which can easily lead to compensatory force in the lower back, and may cause lumbar disc herniation or lumbar muscle strain in the long run. The physiological curvature of the lumbar spine is more pronounced in women than in men, and some individuals with insufficient core strength may increase the burden on their waist when quickly standing up. It is recommended to use movements such as abdominal compression that exert less pressure on the lumbar spine, combined with flat plate support to enhance core stability. Pregnant or postpartum women should avoid traditional sit ups. Performing this exercise during pregnancy may increase abdominal pressure and affect the fetus. If postpartum women have rectus abdominis muscle separation, sit ups can exacerbate the degree of separation. Patients with pelvic floor muscle relaxation who do sit ups may experience stress urinary incontinence. This group of people is more suitable for Kegel exercises or modified abdominal rolls, and should gradually resume training under professional guidance. When women engage in waist and abdominal training, they should choose their movements according to their own situation. Beginners can start by rolling their abdomen 10-15 times per group, with 3 groups per day, and cooperate with respiratory control to avoid neck compensation. Three days before the menstrual period, it is recommended to pause abdominal compression exercises. Patients with osteoporosis or lumbar spine diseases should consult daily to increase protein intake to help muscle repair, and combine low impact exercises such as swimming to comprehensively enhance core strength. After exercise, stretch the rectus abdominis and iliopsoas muscles appropriately to prevent stiffness.
