got it!
After reading all of the good reviews here, I got the DVD (buns, abs, arms). I've done arms and abs and really like it. With arms, she moves fast so you think you need a light weight, but should probably try a med-heavy weight to see results. It can get boring, but moves fast so it's fine.
The abs is great because she adds some new, effective moves.
Tamilee looks great (although I do keep staring at her to see is she's had a facelift or her eyes done!)
On the dvd, there are also sections on nutrition, diet, the science behind the moves, and q&a.
The one reason I'd like a video tape vs the DVD would be so I could stop the ab section halfway thru and pick it up the next day- 15mins is too long for abs somedays.
For the price, I'd get it for those "short on time workouts"! (got mine at bn.com- free shipping if you buy 2 items)
