Insanity or Rev Abs? I've got two months to decide ( rev abs will be launched in October).

Olga, why not both?!
I have to say, Insanity is very challenging(in a good way). It has a lot of potential too. You can use the drills as an add-on to weight routines.
Heck, the 10 minute warm-up and 5 minute stretch is a perfect ending to any weight routine. So many options with this program.
AND I can tell you first hand, I'm on week 3 and the fat is melting off my body like crazy! Everyday I wake up to tighter abs and loser jeans
