Thanks Illa - I'll keep posting!!.
Just done the first of the 30 day shred - not too bad, managed to keep up most of the time although I didn't have any proper weights so am going to get some tomorrow and try again, I'll keep you posted how I am doing, not sure I'll move up to level 2 until I can do all of level 1 ok, but like dthe fact it was only 20 minutes, was over in no time and makes it easier to fit in!!!
