It took me awhile, because I was actively trying to find a forum that talked about fitness and especially fitness videos. This is when I first was buying videos in the stores (mostly Bob, Jillian, 10 MTF dvds and some yoga/pilates stuff). I did some googling, and weirdly I didn't come across it right away. I kept finding other fitness forums, most of which weren't even very active. I found Collage video, and then between that and some Google-Fu I was able to finally locate an active forum dedicated to home fitness lovers!
Then through you guys I discovered Cathe
and now I'm addicted to her forum as well!
