this should feel good right?

I was so excited to get a 30 minute walk in today. I had tried before to do it this week but, could only do 20 minutes. I decided to walk in my back yard and around to the front and up my little hill. I could feel it after 15 mintures in. I think monday I will do some shoulder exercises for my weak muscles in that area then go walk in the yard. It is funny because I carry two bottles of water for weights while I am doing this. I have another bottle of water on my back porch so I can grab a drink while I am walking and still give my muscles a good workout. after about 20 minutes it was much easier to go over the hill. it is not really a hill. I will have to video tape it to show you. I have a lot of wholes in my front and back yard; it is hard to watch my step sometimes. I was so tired afterward to. I feel much better now that I did not stop at 20 min. like I wanted to. I just pace walked instead. Sorry I no I am going on and on but, I am just excited!
