I have never worked out before, but I started doing Debbie Sieber's Slim in 6 about 10 days ago. I am hooked! I picked mine up on eBay for about $20, not willing to pay Beachbody's prices.
I stayed on the Start it Up level for 9 days and just moved on to the second level, Ramp it Up, today.
A lot of the reviews call it boring, but I felt like that was what I needed, since I was a total beginner. I am not bored yet, and my body caught on a lot more quickly that I thought it would.
I have been pregnant or breastfeeding for the past 7 years, including back to back pregnancies where I spent nearly all of 2010 and 2011 pregnant. That did a number on my body, and my knees in particular, and I was worried about a lot of the workout videos that were highly reviewed on Amazon being too high impact for me. These aren't, and bad music or not, I love them.
I am also working out when the kiddos are sleeping, which was another reason I couldn't do high impact - its too loud! Our house is small, and all of the bedrooms clustered together. I work out in the smallest bedroom with kids sleeping on either room on the side of it, and haven't woken them up yet (knock wood).
