Get the Basics…

  • It is important to find information online and on websites that is based on research and is factual.
  • There are numerous websites that provide articles, helpful tips, videos, resources, and even fun information for exercise and fitness professionals.
  • Bookmark the websites in this article or follow them on social media for easy reference.

The internet has a wealth of online resources for fitness professionals. Sometimes it can be difficult to distinguish factual and reputable information from myths and misconstrued information. Always check the credentials of the website and/or author, refer back to the research, or review the information yourself to determine if it’s reliable.

Here are 35 of the best fitness websites for exercise and fitness professionals. These websites are informative, engaging, and full of online personal training resources. Be sure to bookmark these websites for future use.

Exercise.com is simply the best. We were using three or four different apps or softwares to do what we can now do all in one with the Exercise.com platform.
