CT... I know you have said it does not matter what abs exercises you choose but how you execute them. I found in a previous spill that you mentioned which abs exercises you liked to use. I was wondering if these were still the ones you were using or if you liked different ones now.
Here is the list...high pulley cable crunch on a swiss ball, standing cable crunch, swiss ball crunch with a dumbbell on the chest...garhammer raise, double crunch, swiss ball crunch, hanging leg raise...kneeling cable crunch + swiss ball crunch, serratus crunch with legs elevated + knees pull-in.
The reason I am asking is because I have a hard time "feeling" my abs work during ab work.
