Weblogs linked to reputable schools and organizations can be a source of useful information on these topics. Here are some that have been reviewed by librarians:
General Fitness topics
Medline: Health and Fitness - A wide range of information on exercise and physical fitness topics from the National Library of Medicine.
Exercise Library - a "comprehensive library of exercise and anatomy info, including core, full body, and stretching exercises" from healthline.com. Healthline claims their material is reviewed by "experts," but finding out exactly who these experts are and what makes them experts is difficult - use your own discretion when consulting or including information from this site.
Plyometrics
Plyometrics - from Harvard Health Publishing/Harvard Medical School. This is targeted more at the general public, but contains a clear introduction and some basic exercises.
15 Plyometric Exercises - from Self Magazine, again targeted at the general public, but with excellent descriptions and illustrative videos.
