Getting into shape is hard!

So I am trying to get back into shape. I am not trying to lose weight I am trying to build muscle so everyday after I get the kids down for a nap I put on my work out clothes and start doing yoga or this other work out DVD that I have. I have to say I feel a lot better through out my day but it is so hard! My goal is to to be able to do the hand stand part on my yoga DVD so I will let you know when I am able to do it and I will even post pics. So you should hear back from me in about a six months to one year. :) I might even post pics of my attempts just for a good laugh!
