P90X Round 2, Day 5: Ab Ripper X

As I now seem to be able to complete all the moves, my principal focus is now on form. I am trying to keep my chest up high during the first few moves (in and out, bicycles, crunchy frog) and engage the core; straight legs on the fifer scissors; straight legs on heels to heaven; going straight up before crossing over on the crossed leg situps; maximum back lift during pulse-ups on VF rollups; straight legs and maximum bend on oblique V-ups; straight, high legs when leg climbing; finally, extending the legs out straighter during the mason twists.

I achieved some of those objectives; the task is to improve on every exercise and to be consistent. Now, Ab Ripper X is more of a mental challenge for me.
