Fie--Hope the move is going ok...I can say that I hope to never move again, it is a hastle. I have never tried an ab glider thing but if you see result it must be a good thing, keep up the hard work and fitting it all in with the chaos going one.
Sillymommy--You will benefit from both types of fitness, if you run shorter distance but at a high rate of speed you really work those muscles, if you go longer distance at a comfortable pace you work your endurance and your heart more

One thing to keep in mind is, you will burn about 100 calories per mile weather you walk or run it. Also, the more effort you put out in anything the more results you will get. Why not mix it up, do a long coforable run sometimes and other times do a quicker shorter run, eventually the two will come together and you will be run long and at a faster pace
