More harm than good today?

Well today I did another lower body workout and even though I was just a little stiff from the Sunday workout and run I was not all that sore so I figured I was ok to get through it. I also added some weight to the lunges and to the leg extensions this week so my legs to feel tired but not as worn down as they have felt in past workouts. I don't know if this is a good thing letting me know that I still have yet to add a little more weight or if I did more harm than good by not letting my muscles fully rebuild before working them out again. I guess we will know in the morning. Tomorrow I am going to at least start my day from the house if not work the whole day since our new couches are coming in and I would like to be there for that. We ordered them back in September so it has been a while since we spent the money on them. Tomorrow weather permitting I will be running around the neighborhood rather than on a treadmill. I am pretty happy about that because it will give me the chance to let me start building my endurance back up for long distance runs.  I figure two laps around the neighborhood will be just over a 5 K and I should be able to do it in under 30 minutes so I won't be straying from the Body-for-Life formula all that much. One thing that has had me confused is to why all day the last two days I have been getting hungry not just a little hungry but really hungry about an hour before my next eating is supposed to happen. Since getting off the planning of meals I have not strayed from the actual diet, I still eat six times a day and get a portion of protein and carb at each meal. I suppose that as my muscles grow so should my portion size. I am going to hit up the Body-for-Life forum that I have been following and see if anyone else has been going through this and see if they are thinking the same way that I am. I kind of hope that I need to add bigger portions but I am also a little worried to since I don't want to put on fat while I try and put on the muscle. Well tomorrow is going to be a good day and I look forward to the run as I always feel great after a run and start my day off in a great state of mind after a nice long run. I guess we will see if the rain has left and I can do just that. I am telling you now that I really hope so.
