Query: Another winner from Jackie

I have all of Jackie's workout videos, and they just keep getting better. Her crunchless abs workouts have replaced all of my ab work at the gym. The floor workout is very challenging and focuses a lot on planks and plank variations. I like the standing workout, which focuses on a lot of twists and makes my obliques sore the next day! She offers unique moves that are both challenging and fun, and I find her instruction to be spot on. Also, the two women who work out with her have fun personalities that make the video that much more enjoyable. This video has no real repeat exercises from previous videos, so whether you have all her videos or have never worked out with her, I highly recommend this video!!
