When doing sit ups, is it better to exhale as you come up or fully exhale after your elbows touch your knees?

Question

Is it better to hold your breathe while coming up and then exhaling fully when you sit upright or to gradually exhale as your are coming up?

I need to do 35 quick situps in one minute for a physical fitness test and need to know the proper breathing technique for best results.

Thanks to all who respond.

Gotta watch the pressure. Dont want to blow out your O-ring. Breath- out on the crunch stroke.
