Hi kel!
Well let me start by telling you, your in the right place.
Since i've discovered Cathe's workouts, there just is no comparison to other videos.
BUT, let me also forewarn you: Your going to want more.
I know, I said it when I started out too, "i only need one or two" but, your going to enjoy these workouts so much, your definately going to start wanting to purchase more.
So, don't forget to hop over to videofitness to join the other fans.
But, i highly suggest you take advantage of cathe's deals, the buy 4 get the 5th video free. I didn't do that when I started out, and ended up acquiring them one by one through exchange, and other sales etc.. I would've much rather had 4 or 5 all at once.
Good luck!
