Is this progress that I'm seeing?!?!?!?!?

I hope everyone had a wonderful memorial day weekend! I know I did, it was my birthday sunday and I can be honest and say I put down quite a bit of Korean bbq:). But I also worked out friday, went swimming sunday and monday decided I would take my dogs for a little run. I have my usual 2 mile route I take them on, but instead of just walking I ran one block and walked one block. I was pleasantly surprised to see how much my endurance has increased since I started p90x. I actually felt like I could have gone the whole way without stopping, but my dogs were getting tired. I didnt want to wear them out to badly, plus I didnt bring water. I can honestly say it was very enjoyable and I'm not even that sore today. I think I'm going to start throwing in some runs a few times a week. It's exciting to know that even if the scale isnt moving like I'd like it to, my body is getting stronger and I'm getting back in shape:) yay for small accomplishes.
