I have a Bosu that I purchased from Costco about 2 years ago it came with 4 DVDs - Bosu Absolutely Abs w/Gregg Cook, Bosu Balance Trainer, Bosu Long and Lean w/Chalene and Bosu Calorie Combustion w/Rob Glick for $50 and I finally got around to using it. Right now I'm using it with my Supreme 90 rotation and Tracey Staehle's Parts Series.
I love it for core work sometimes I'll use Cathe's Core Max with it when I don't feel like using my Stability Ball. I think when I'm done with my Supreme 90 rotation I'll use the DVDs that came wth it.
For me it is one of my best Fitness purchases.
