Bests & Worsts Reviews from Amazon

I'm a senior, watched Miranda on PBS, was interested in mobility, bought this workout. I'm disappointed that Miranda doesn't suggest "if you're new to stretching, don't worry if you can only move this far" or "be sure your knees don't go past your toes" (it's harmful to your knees to do so). Maybe there's a beginner DVD of hers that I should have purchased instead. I'm disappointed with the lack of instructions for doing the exercises and disappointed that I felt she was only speaking to experienced people rather than including all levels of fitness and experience. I don't recommend this, check out You Tube instead.
