This series takes a look inside the human body and its processes as it exercises. Chapters cover the body?s response to exercise, optimal gain, potential health benefits and drawbacks, and modern advances and developments. The books also contain an introduction, plus further research and more information sections. While the titles provide ample information and action photographs, the series lacks continuity and consistency in regard to writing style and content focus. Advanced readers with an interest in the human body and exercise should benefit from this series. Bibliography. Glossary. Index. Additional Selection.
