Cautions with Sit-ups

Exercise Tip of the Day

Full sit-ups can be a problem because the hip flexors attach to the lower spine, so doing a lot of sit-ups can cause or worsen low back pain. This is why crunches, which engage the abdominals but do not involve the hip flexors, are usually recommended. Crunches are safe for most people, but you should never do any exercise that causes pain.
