I tried to find the rules - I'm hoping this isn't against them. I also don't know if these have been mentioned before but I couldn't find anything on them.
Two sites that I enjoy are:
Here you can swap or sell your exercise workouts that you no longer want.
www.videofitness.com
I also really like the reviews they have for the instructors and the workouts.
and of course
www.collagevideo.com is a good place to go for reviews on workouts also.
Again, I hope I'm not breaking any rules by posting these. If I am, I apologize and understand the deleting of this message.
If it's not breaking anything, I hope the sites are useful in your exercise journey. I love to exercise (even though my body doesn't look like it! LOL).
