Learned earlier today that Beachbody's begun to make previously purchased workout programs that aren't in the regular Beachbody On Demand library available. So far it's limited to Focus T25, 21 Day Fix and 21 Day Fix Extreme, but now that these are up I'm sure it won't be too long before more get added.
If you're a club member, click the Beachbody On Demand button and at the top you'll see "Purchased Programs", and the eligible programs will be listed there. The launch library of 10 workouts is below that.
Here's my signup link, or go to teambeachbody.com directly and sign up for Club membership.
(note that as I type this, the website is down.)
