I wanna join the party!!!!

I lurked on this board last week, looked up the program, Tues I bought the Itunes app, and off I went. I did W1D2 today, and I totally hated the first 10 minutes. I know myself, and I know I will never get to the gym. With 2 girls, working on my Master's Degree, working full time, and taking the oldest to her competitive gymnastics 3 days a week, 45 minutes away, it's just not happening! I have to run outside. Trying to find a place that is not so hilly. All the roads around my house are killer!
Some background, I am another one of those wii fit obese ones. UGH! Lost of a lot weight, 65 pounds, 4 years ago. Found out I was pregnant with our second child, (never thought it would happen, had to have fertility drugs to get first, total roller coaster, horrible experience), anyway, slowly crept the weight up during the pregnancy and never got it off. Didn't gain back all 65 pounds, but close to 40. I've gotten rid of 5 over the last year, but I want it off. NOW!!!!!! My goal is to lose 35, then see how I feel/look from there!
Couple of questions.
1) Anyone have any suggestions on how to get my breathing under control? I am huffing and puffing soooo badly.
2) Any great running songs? Using the c25k app, I can put my own songs in. Running to some of the rap stuff, works well. Think college football warm up songs!
3) What do you do on your off days? I did 40 minutes on wii fit yesterday, which was fine. I would like a more ab/core intensive program, and a good yoga video. Did the big ball stuff when I lost weight before, I liked it, but my girls popped the ball, and it's not destined for my house for a while. Has to be inexpensive, not take up room.
Think that's all for now. THanks for reading my book if you made it through!
