Sit-up (Exercise)
The
sit-up
is a
strength training
exercise
. To perform it, a person lies down on the floor with their
knees
bent, and then sits up without moving their knees. It is intended to work the
abdominal muscles
, but it also utilises the
hip flexors
. The hands are placed behind the head or across the chest. The sit-up places considerable stress on the lower back
vertebrae
, so individuals who experience lower back pain should perform the
crunch
instead.
