I have TransFirmation kit and I did have problem at first but I did the modified version and take 5 second break if I had to...but didn't stop and kept moving. Keep up at it and you will get used to it. If it's too difficult at first, you can try the Express one too. (not sure if we are talking about the same ones...)
and I agree with Nish. You will notice improvement in just a week, really. =) Keep at it and you really will see result, too. Mine did prove its worth after 10 workout, like it promised.
