Sit-ups vs. Crunches ? Sit-ups and crunches are sometimes used interchangeably, but there are some noticeable differences between these two exercises. The two exercises work the abs differently , and sit-ups are generally a larger movement compared to crunches. Crunches mainly exercise the abdominal muscles, and the hip flexors may also be engaged. Sit-ups involve using other stabilizing muscles in chest, back, neck and hips. A common mistake when doing either crunches or sit-ups is to primarily use flexors instead of abdominals. Because sit-ups tend to involve more muscle groups, if someone has a neck or back issue, sit-ups may be contraindicated . Some people may say sit-ups bother their neck or back or both more than crunches because crunches rely less on these muscle groups... In this case, crunches would be better than sit-ups. Crunches in general tend to be more popular over sit-ups because the movement is smaller but with the same effect as a sit-up. Some people have a hard time sitting all the way up regardless of abdominal strength. ( long torso vs. short torso) Mrs. Lifestyle
