Why Tens of Thousands Flood to Nerd Fitness Every Week

This is an old article on Detailed.com that has been since removed. I had saved the article in my RSS Reader and writing this summary based on it.

NerdFitness is a site that helps Nerds lose weight and get fit. The interesting thing about the site is the forums that have a category called ‘4-week challenges’ where people document their progress with a fitness goal and have accountability from others.
It’s an incredibly active area of the site. People are flocking to these challenges and love them.

Creating challenges is a great way to create a community and have an engaging audience. Having a forum is not a requirement, you can even do it in Facebook Groups nowadays.
