I’ve seen this comment posted a few times that people don’t know this, so I thought I would just make a post here!
If you are a member of Netflix, you can try a whole bunch of exercise dvds. Just go to the Genre tab and look under Sports and Fitness. Then choose Workouts and browse away! It’s awesome because you can try and discard without having to actually make a purchase and dislike it. Then if you really like the DVD, you can add it to your collection.
