Does doing sit-ups harm the lower back?

Whether sit-ups harm the lower back depends on the specific circumstances. Proper technique generally does not cause injury, while incorrect form may damage the lumbar spine.

1. Correct technique

Sit-ups are abdominal exercises that use the strength of the abdominal muscles to lift the upper back and lower limbs off the ground. When performed appropriately and correctly, sit-ups usually do not harm the lower back, as proper form avoids stressing the waist and prevents compression of the lumbar spine.

2. Incorrect technique

If sit-ups are performed with improper or incorrect movements—such as using the hips as a pivot point—bending the upper body can easily compress the lumbar spine, potentially causing injury and negatively affecting overall health.

It is recommended to consult a professional before performing sit-ups. Exercise duration should not be excessive—around 15 to 20 minutes is sufficient—and proper warm-up exercises should always be completed prior to starting.
