She has a couple I think, I've got the 30 day shred.
Thankfully she isnt anywhere near as nasty on the DVD as she is with the contestants!
I've read a lot of comments from people who think this DVD is amazing - I cant really comment as this is the only one I've ever done, so I cant compare it to anything.
It is very hard, it comes in 3 levels, i've done the first 2, but must admit I've got a little fed up with doing it, so have ignored it for a couple of weeks.
I would say it probably has made an impact, you certainly feel like you've had a work out afterwards, I've just got a little bored of it. It only cost me £5.99 on Amazon though, so I dont regret it.
I've decided to try doing the couch 2 5K running programme instead so have decided to drop the DVD for a while (I still go to the gym about 3 times a week as well)
