Hey guys I got my routine pretty much figured out but feel like my ab work outs may be a little plain. I really don't have the nicest abs but am very motivated to work on it. So far I do abs 3 times a week. On my ab day I'll do 3 exercises at 4 sets and 20 reps each. I'm doing ball crunches(sometimes I'll hold a weight) cable crunches and leg raises. I'll turn to the side when I crunch upwards to try and hit the sides as good as possible. So anyway I want to know if this is sufficent or if I should try something different? Thanks alot for any help!
