Ex Input:
If you are not in really good shape this is a great product to get ready for P90X. It does get kind of boring because you are doing the same workouts every other day, but they do work. It is only about 30 mins but it is amazing how well it works.

Ex Output:
Positive

Ex Input:
A new wave. The strongest part that brings you back, is the creative flair of the music. The music can stand by itself. Just really cool, float me away.
