I originally came across the LifeFitter website after clicking on a Facebook ad related to the Outpacker.com website.
After being thoroughly impressed with the design, thought and execution of the outpacker network, I discovered that LifeFitter is behind a network of 20 affinity based social networks, all geared around mostly outdoor, sports and recreation hobbies.
If you enjoy anything from kayaking, to paintball, to mountain climbing or biking you should uncover more of what they have to offer and expand your network with more sports enthusiasts that love the same thing you do.
If you’d like to see all the sites available you can also review them on my personal blog where I wrote up a post about this site’s use of social media.
