Bro...on the exercise ball...sit on it and make sure it is up against a rail or something you can hold on to, maybe a bench. Now roll on it as if you are going to do a crunch. Hold on to the bench or rail and you are going to do leg raises. It is a bitch to keep your balance at the begining but you are using all your stabilizer muscles here. Bring your legs up and lower in about 3 seconds. When your legs are straight (slightly bent of course) and parallel to the floor hold for 3 seconds and come right up. Try doing 15 reps like that...If you can...Ten will be good too...
Ask anyone who thinks they have strong abs to do that exercise....ha ha...They will nto be able to...But once you start doing it, you can get strong and able to control yourself on the ball very quickly. I like doing lower abs first, then crunches, then obliques!!!! Enjoy...
Leg raises on the floor or off of a bench is nothing like doing them on the ball...Have fun
