Query: A few comments

I have viewed the two-tape set, and I enjoyed it. The basic workout is good for someone who is just getting into working out, because it is short and reasonably intense. I agree with other reviewers that the production quality and music could be improved!I have some comments in response to some of the other posts:1. Regarding the length of the basic workout -- if it isn't long enough, use the time function on your VCR, rewind it and do it again.2. So what if Billy doesn't mirror your moves? If you have trouble keeping the left-right instructions straight, start with one side then switch. Each set is separated with marching, and he consistently alternates sides. I really don't understand the big deal about this.One of the things I really like about this tape is that Billy shows the viewer how to modify the moves to suit someone who is just starting out. Between that and some common sense, I think most people can develop an exercise routine that fits their needs.
