Well as long as we are going to talk about Amy, let me just put in a glowing recommendation for her new KB2 workout. It combines intervals of kickboxing with kettlebells, it is almost entirely low impact (there are some optional jump kicks), and I work up a crazy good sweat. The kettlebell intervals are not very long and add a nice element to break up the kick box routines, the kick box routines are just complicated enough to make them interesting without being too difficult to master pretty quickly, and it does not feel like you keep doing the same move forever. The music is good not great like some of her others, and a big plus for me is she does the workouts barefoot which I love. It's the kind of workout I look forward to doing because it's fun and feels like I am accomplishing a lot.
Only one issue, there was a problem with the first round of dvds sent out, so they are not shipping any more orders until they get the newly pressed dvds in to fix the issue. But when it's available, I highly recommend this DVD.
