In the training schedule, the most important is regular and equitable for all the muscle you have, although the aim is to form the Six Pack.
Try less than in session 1, big muscles get 9-12 sets of small muscles of the core and get a core set 6-8. Then order the big muscles first and smaller muscles, unless you train 5x a week so you can split apart as in the example below.
Another thing to note is that in practice is a break between sets is 1-2 minutes. This is very important to keep pumping and muscles expand during exercise. Thus the total time spent in the weight training 1 session 45-60 minutes in enough. Examples of training pattern :
