The physical fitness test of college students lasted for one minute, with 26 freshmen and 26 sophomores passing and 27 juniors and seniors passing. College students only have sit-ups for girls 1 minute, and each student is assessed once every academic year, which is recorded in the National Student Physical Health Standard Registration Card.

Before the test, the subjects crossed their fingers behind their heads, their legs were slightly apart, their knees were bent 90 degrees, and they lay on their backs on a flat mat. Another companion pressed both ankles of the subject to fix the lower limbs.

Matters needing attention in sit-ups

Proper sit-ups involve gluteal muscles and abdominal muscles, which need to arch the back and easily lead to spinal injury. In addition, the lever force exerted by gluteal muscles will also compress the lumbar intervertebral disc, so suddenly doing sit-ups excessively will definitely lead to the compression of the lumbar intervertebral disc and even damage the spine, further aggravating the condition.

For those who are just starting to do abdominal muscle training, it is best to do sit-ups in groups, and the number of times at a time should not exceed 10, which can be gradually increased in the future. The total amount of exercise in one day is that there will be no severe muscle pain the next day.
