Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Save your money

Luckily, I only borrowed this video. You can do 10, 20, 30 or 40 minutes, but they do not explain the moves at all or give you time to learn them before jumping right into it. When you work out for even the 10 minutes, they play the same moves on a loop...boring! Also, It's hard to exercise with you're feeling really annoyed by the instructor who cannot lead.
