Am I Doing The WRONG P90X?

My girlfriend just told me there are THREE P90X series.  Classic, Lean and Doubles.  Well I knew about the Classic and Doubles, but how did I miss the LEAN? 

Regardless, I will continue doing the CLASSIC.  I'm really not trying to LOSE anymore weight, just firm up and gain some strength (( yeh baby )).  I was sooooooooooo proud of myself today.  I added between one to five reps with each exercise, including my AB Ripper.  My form usually BOTTOMS OUT, when I get to the last TWO exercises.  I was able to keep up and my form .... may I say, "WAS OUTSTANDING!"

I made sure to breath through each exercise (sometimes I tend to HOLD it).  As crazy as it may sound, I'm DIGGING the PAIN.  It's no where near the way I felt last Monday.  It's just a dull PAIN, that let's me know that my BODY is ALIVE!  Those that have started this journey know what I'm speaking of.

Can I say, "I BRUNG IT !!!"
