If you can do any strength exercise for more than 15-20 reps, then you are wasting your time.
To crunch:
Lie on the floor with knees bent.
Start with hands on chest (you can stick them out behind your head later to make it harder).
Press the small of your back into the floor.
Whilst still pressing that, pull you stomach in through your belly button.
Whilst still pressing the small and pulling the stomach in, raise your upper back off the floor in the direction of straight up, i.e. push your head towards the ceiling, not towards your knees. Your head and neck will be about 4 inches off the floor.
CHECK YOUR SMALL AND STOMACH CONTROL NOW!!! DON'T LET THEM LAPSE. REALLY CONCENTRATE ON PULLING THAT STOMACH IN AND CRUNCHING IT.
Hold this position for 5 seconds whilst maintaining core control.
SLOWLY lower yourself back down to the floor, retaining core control until you are fully flat on the ground.
Relax for 1 second.
Repeat.
If you can do this more than 15 times without your stomach feeling it's going to explode, then your technique isn't dialled - try thinking about crunching you stomach up into a little ball while you are holding in position for 5 seconds.

Most of the action on situps is wasted - after you reach 45 degrees, your stomach isn't doing much at all.
