To do the correct movement lay flat on your back with an abmat or rolled up towel under your lower back.
In the traditional off the floor sit up the feet are anchored and the hip flexors do much of the work.
With the abmat a proper sit up can be done with a neutral spine and without momentum enabling a more complete range of motion and more effective conditioning.

The abmat sit up is wonderful to develop full spinal range of motion abdominal strength so that a person can start to think about getting on a ghd.
It also helps develop cursory strength for toes to bar and knees to elbows and gets the abdominals thinking about midline stability during barbell movements and pretty much everything else we do.
An improper device will not give the proper support bend the knees about 45 with heals on the floor.
One of the first exercises i did when i started crossfit was this move called an abmat sit up named after the mat you place under your lower back for support.
The back is arched in an unsafe position and momentum is what finishes the movement.
