Finished Core my last full day of vacation (Friday). I didn't necessarily dog it, but I have to admit that I wasn't in the frame of mind to really put my all into it. I got through all the exercises but I fell apart during the Plank/Chaturunga runs and iso's. The Sphinx push ups were harder than I remembered too.
Saturday/Sunday was supposed to be Kenpo/Stretch. I knew I was going to be driving 12 hours on Saturday, so I switched Kenpo to Sunday and essentially just skipped Stretch. The Stretch workout is only done once during each recovery week for a total of 3 times during the 90 days. It is also optional as the 7th workout every week. Practically all the stretches in the workout are already covered in the warm-up/cool-downs of the other workouts so I don't feel like I really missed anything. However, just to be good I plan on putting Stretch during my next off day so I can officially say I haven't missed anything.
Did Kenpo yesterday as planned. Nothing really new here. Kenpo is the easiest of all the workouts for me. I've continued to toy with replacing it with Core every week. I see from internet searches that others have done the same thing. The problem with that is there would only be 48 hours of recovery from all the upper body stuff before I'd have to do another round of upper body with either Chest/Back or Chest/Shoulders/Arms. It is really hard to tweak the P90X schedule without running into issues with recovery.
