Hello everyone. I had a question. I used to train my abs...i had 6 exercises i did...and i did each exercise for 1 set...but 40 reps for each exercise...so i did 240 total reps. For example:

crunches: 1 set...40 reps
Hanging leg lifts: 1 set..40 reps...and so on...

I tried to split my abs into 2 sets tonight...for example..

crunches: 2 sets...20 reps for each set
Hangling leg lifts: 2 sets...20 reps for each set.

I broke the exercises into 2 sets this time. Does it matter what i do? do i need to split my ab exercises into two sets...or even three? help would be so awesome.
