you mean your lower back? so, i don't think situps would help much, although
it would not hurt.
what would help is a reverse situp. lay face down flat, and raise your leg
and opposite arm, hold for 10 seconds, switch sides, do this for 1 minute,
rest, repeat for 2 more times.
this exercise will strengthen your back muscle, which will help.
