The first week of P90X was sheer pain. After about 3 days into it, I didn't want to move, let alone do another workout. I only lost about 1-2 lbs after the first week, but I built a lot of new muscles. Believe it or not, I've actually been keeping up with my running schedule pretty well even while doing the P90X program. I think doing my running has actually what has helped me loose more weight than the P90X program. My upper body strength is 100% due to the program, but the weight loss and smaller mid-section is mostly due to the running I've been doing.
Some days I do my runs first, but I find it better to do the strenuous workouts, and THEN relax on a nice trail run. Sounds crazy I'm sure, but it works for me. The 2nd and 3rd weeks were hard, but not as hard as the first week. After the second week I'd dropped 8lbs (total) and after the 3rd week I was down 12lbs total. This last weekend, I weighed myself and I was down 15lbs!!
I actually did the 3rd week twice. We were in the middle of getting our house ready to sell, so on Thrusday, rather than killing myself with guilt to get in a run, a workout, clean the house and yard, write code, and also sleep, I decided to just take the 1+ hr 'workout' out of the plan. It worked out great because I was able to pick right back up where I left off after we had our open house. That next Monday was back on track so I guess you can say I got in 3 extra workouts. :)
Yesterday was my first day in Phase 2 and it SUCKED! I was weak, I was sore, and I was sweating like a fool. Today my muscles are very sore, but I feel strong. I am anxious to get into the 2nd and 3rd weeks of this Phase 2, for I know I'll be ready to keep up with the program once I get past these sore creaky muscles from week 1.
So between my P90X and my 25+ miles a week for the last month, I'm kicking butt and I'm really not that scared of the 100k race. I'm anxious, but I'm not scared like I was in June. :) By the time it gets here (October 16th or 66 days from now) I am hoping to be down to 185 lbs or so. This will mean that I'll be floating through the trails in my VFF's with 35 less pounds. I will earn this buckle:
