Tais challenge is really exciting ! The first two classes gave me a feeling of "freshness". Isn't it possible to take two classes by day ? I'll have to travel without possibility of training before 8 days, and I'm sorry to have to interrupt the challenge...
Evelyn ~ Unfortunately these videos can only be unlocked one at a time. If you are interested in doing more than one per day, you can try repeating a class and then adding the new one after or you can supplement with another one of Amy's classes. I hope this helps!
