Query: Worst exercise DVD ever - don't buy it

Save your money, or you'll end up watching a DVD shot by a 5-year-old in someone's dimly-lit basement.The exercises are not well explained, and you can't watch them either because the instructor is wearing black pants and what look like black tights against a dark grey, dimly-lit floor - so any nuance is absolutely lost. I just couldn't figure out what she was doing, and again, her instructions are worse than poor.The ab work is very similar to 1980s ab work, hard on the neck, and not necessarily proven to streamline the core. I have avoided this type of "crunch" ab work for years because so many instructors provide better and more proven alternatives.I wouldn't call this DVD a workout; just a random selection of exercises done in semi-darkness.There are better ballet-inspired workouts on Amazon; buy them and skip this.
