School of Recreation and Sports Sciences, Ohio University, Michael R. Kushnick, PhD, HFS, Assistant Professor of Exercise Science -- I believe the...textbook is perfectly suited to health fitness practitioners who may have less current physiologic background?they are further removed from their training and have more "on the job training" and less course work in biology and physiology. University of Florida, Christine Stopka, PhD, Professor, Department of Health Education and Behavior University of Florida -- "The text reads so easily and smoothly. It is not tedious. It reads quickly but is still packed with content. It is a joy to read and makes learning fun." Chatham University, Carena Winters-Hart, PhD, MPH, Assistant Professor, Department of Physical Therapy and Exercise Science -- "This text is ideal for undergraduate exercise science students and those who are independently working in the personal training field."
