Week 3 almost over

I am so glad that week 3 of the P90X program is over; I have been extremely tired this week, and have not done a good job. Last night I was exhausted in the middle of Kenpo X. It all started after I ran that 5K race last Saturday; it threw me off schedule and I had to kick ass to get back on track after that. My average heart rate, speed and endurance have decreased this week. Not good. P90X is very demanding, and I think I will have to take a closer look at my diet from that point on. Today is rest day so I'll try to come up with an Excel sheet that automatically calculates the amount of Protein, Carbs and Fat per type of food your enter, and tells you when you have reached the P90X threshold depending on your level I, II or III.  If it works, I'll post it on this blog.
