21 Day Fix Dilemma

So....I've been doing P90X3 for the second time.  I am enjoying it and have two months of the program left to go.

The dilemma?  I got the 21 Day Fix and 21 Day Fix Extreme in the mail yesterday.  It's new to me...  a lot of other people I have in my groups are doing it and loving it... and I'm excited to start.  Why is this an issue?  Because I want to drop everything and start the Fix!  The question I was having was, do I finish X3 first?  Do I finish X3, but use the container system from the Fix?  Or do I just say, "forget X3 for now, I want to play with my new toy!" ???

When I posted this question on my FB wall, I did get a couple of requests to start on the Fix so that I could review the program.....so......  my arm has been twisted.  I'm going to start the 21 Day Fix on Monday and post here about my reactions to the program and my progress.  It's only 21 days, right?  I can always rotate X3 into my routine elsewhere.  I'm not looking at it as giving up on a program.  I just used it temporarily between two other programs and will come back to it at a later date.

Now....time for me to become familiar with the container system (I already calculated which calorie bracket I fall into and how many of each color I should have each day).  I just need to actually look at what foods I should be eating more or less of....
