While I agree that going to a studio for Pilates or yoga is ideal, it's not feasible for everyone. Factor in how difficult it is to filter out inexperienced instructors - yoga injuries are skyrocketing with its popularity. A single group class in my area costs as much or more than a video.
Debbie, since you like a faster tempo, I'd suggest Karen Voight's Body Reform abs & back. It's Pilates inspired & I've criticized it in the past because Voight rushes the moves. But I think Jennifer Kries (The Method, etc.), Moira Stott, or Suzanne Deason might bore you. They're all excellent Pilates instructors but might be too low key for you.
