I've done it- I liked it- we stopped during the holidays because we (my husband and I) both got sick at different times and then with so much going on we decided to restart in January. We did it for about 5 weeks.
You don't have to buy the pull up bar. I recommend a few different sized weights (we have 3,5,7,10s), we each have a resistance band, a yoga mat, and that's really it. We already had the weights and yoga mats though- you can use the resistance bands in place of the pull up bar. Get the resistance band that has the piece you can put in between the door and door frame. It works for us. I noticed major differences after a few weeks (slimmer arms, tighter abs).
I definitely recommend it- my husband and I are restarting in January (I'm restarting with or without him).
Also there are over 10 DVD's, (I think 12 or 13), so it's quite a bit of different ones, usually you only do 1 of each DVD per week, so it'll take a while IMO to get bored of it. If you hit the music option you don't have to hear the host say the SAME things over and over
Hey Karen I just realized it's you! lol. Hi
