There are many great workouts that will help you get six pack abs, but my favorite is a bicycle crunch. It works all your abs and at the same time it gives you that finishing touch of the V cut. This answer is good too but you did not list the workouts that the person asked for in the question. I think workouts like Pilate's and crunches and stuff like that should help. going for a swim is good ab workout plus its a hole body workout and it will help you cut down fat in your abs and also doing around 15 minuets of skipping ( with ropes) will help tone your abs if you flex well doing it .
The answer to your question would be to go sixpackfactory.com. They have multiple workouts that hit the abs really well, and can help you get the abs you want.
