The workout changes up a bit in Phase II, and don’t forget I will be adding in High Intensity Interval Training (HIIT) which is not a part of P90X. The routine for Phase II runs as follows:
Day 1: Chest, Shoulders & Triceps, Ab Ripper X (ABX), HIIT
Day 2: Plyometrics
Day 3: Back & Biceps, ABX, HIIT
Day 4: Yoga X
Day 5: Legs & Back, ABX, HIIT
Day 6: Kenpo X
Day 7: Rest or Stretch X
Due to the intensity of the workouts and my need to increase my caloric intake, I am breaking my workouts up. I began with Chest, Shoulders & Triceps. I then ate a meal, took a break and then performed ABX and HIIT.
Chest, Shoulders & Triceps is brutal! When the time comes I can make it through that routine I will be giving my U.S. Marines a run for their money. There are no pull-ups here. It is all weights and push-ups. I spent most of the time on my knees (keep your mind out of the gutter peeps). The variance on most of these exercises I would have never thought of. They are brilliant and worked my muscles in ways I never knew possible. I loved it and I will definitely be feeling this in a day or so.
Because my HIIT exercise of choice is running, and I am scheduled to begin today, it is raining harder than it has all season. Murphy’s Law. So, I pumped the resistance level up to 2 on my Pro Form XP Stride Climber 600 elliptical and got busy. The first week of the HIIT routine is as follows:
5 Min Warm up
6 Sprint Intervals – 30 Seconds each
6 Rest Intervals – 90 Seconds each
5 Min Warm Down
This kicked my butt. I feel good as I sit here with sweat rolling down my face. My lungs are hurting in a good way. This was an intense workout. Because I have been doing cardio for a while, including jogging, I was under the mistaken impression that I could perform this routine with no problem. Oh my goodness, I could not have been more wrong.
Last, but not least is ABX. Yowza! Performed immediately after my HIIT, I paused the tape with each individual exercise and I did every repetition. I am so proud of me. I am ready to vomit now. but this is probably the best ABX workout I have had to date. Though I am still unable to perform every exercise without modification I am so much closer to performing it as it should be. I have gotten so much stronger.
It could be that eating in between routines has improved my performance. I do not know. I do know that I’ve had more lasting energy and stamina during todays routines than I have had throughout the program to date.
Great workouts. Great day!
P90X After 40 
It looks like you are really bringing it for phase 2. Ab ripper x went well for me too. Is it just me or are we getting more fit?!?!
I am doing a sort of doubles too with HIIT. I am kind of addicted to the routine.
By the way, how is the knee doing?
You two are maniacs!!! I feel lazy compared to you two because I’m not doubling up. I’m going to consider hitting the gym and knocking out some HIIT also. I was doing that prior to doing P90X. I may get started this weekend after I’m done with Kenpo X.
Boomer, my knees are feeling good. Thanks for asking. I think it may have been soreness from muscle building. I don’t know.
Hey Big, you look relatively young in your pictures. Don’t feel lazy on our account. I can’t lie, if I had another option I would not do it. LOL.
I’ll be 37 in a couple of months, so I’m not ‘that’ young… I had another great workout today, so I’m gonna at least start doing HIIT on Saturdays, but I may start doing it on my cardio days during the week starting next week. I just want to see how brutal the Back and Biceps routine is tomorrow.
