idk, what kind of abs are u looking for. poeple say i have a feminin body and a female shape/posture. however i have what poeple whold consider "smooth abs" where most men whould go for a body with "hard abs". nontheless, it keeps me fit for the sports i do (cheerleading, swimming, gymnastics etc.) and basically my abdominal workouts are centred around belly dancing. trust me, it's fun and it works. just see the results
I like the inverted crunches, although they're more easily done at a gym with the proper equipment. The general idea is that your ankles / calves are held in place by a padded bar, and you lay face down with everything above your waist hanging off the "table/equipment" You bend down at the waist, then raise yourself back up using abs / leg muscles. You can add weight in your arms to make it more difficult. Also, crunches with a medicine ball, tossing a medicine ball back and forth between two people, and twisting side to side with a medical ball will hit most of your ab muscles.
