What is this "D" that shows up on the Flashcards?
Sometimes, the last part of a move will "double-up" on one side, before going on to the next move in the routine.
When you're ready to Perform It, keep your eye out for the D so you know when it's time to double-up.
If you're having a hard time, try the track in Break It Down. We'll call out double-up moves during Break It Down so you know what to expect.
