One sure proof way to target the abdominals with 1 abdominal exercise is the PLANK aka the HOVER!  The plank or hover never seems to get any easier, but the more you do it you should increase the length of  time for the hold.   Start with a 30 second hold, for 4 sets.  Gradually building up to 1 minute planks.

Another really effective abdominal exercise that targets the obliques is the Side Plank.  Try to

build the time of holding the side plank on each side up to a minute.  Now, for a real 1-2 punch, hold  a side plank, and then turn the body into a regular plank/hover, followed by the other side plank and one more hover.   OOOO-EEEEE are you going to feel that!!  It is very effective combination!
