I don't own any of the Collage top ten but I borrowed and tried 4 of them :)
I really want but will probably just be borrowing Aero Barre: Ballet/Boxing/Sculpting from the Collage New Releases. Just bought Styler's Sculpt & Tone Ballet during Mary's holiday sale. Also already bought Boogie Down the Pounds from Mary previously.
I own "Jeanette Jenkins' Bikini Boot Camp" thanks to the giveaway here. LOL
I want Tonya Larson's Trim & Toned in 20 because I only have one w/o with the stability ball.
I want Tracie Long's Defining Shape from the Longevity series. I really enjoy the Focus series and I think this one looks great too.
Bonus entry: Of the Top 10, I own Jazzercise Dancin' Abs, Tracie's Staying Power, and Petra's Bootcamp Boogie.
Bonus entry: I really want Tracie Long's Step Forward! I will have it eventually.
