I highly recommend this book. It details off-ice conditioning programs for singles, pairs, or dance and skaters of all ages and skill levels. Strength training, effective warm-up and cool down, plyometric, and other off-ice conditioning programs are detailed, as well as effectively improving your muscular and cardiovascular conditioning on ice. The only negative to this book is the photos and text explaining some of the moves - they could be a bit more descriptive.
A great book from a very qualified author. These programs will yield great results on the ice if you put the time and effort in to conditioning.
