my goal is bulking up with wbb1 routine
I m on the wbb1 routine for about 3 weeks now and i really getting good gain..but i m not satisfy with abs..there is only crunch 4x10..
and it suggested to do abs on working-out dayz..(monday,wednesday,friday)

Can i perform abs differently on non working-out day(tuesday,thursday,saturday)??

1.reverse crunch
2.knee to side crunch
3.butterfly crunch
4.crossover crunch
5.V-up
6.crunch
i will do this 2~4sets 5~20reps..
these would be circuit training..do all 1~6 at once and take 2 mins rest..

howz this sounds??
