Input: Consider 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.

Output: Positive


Input: Consider Input: Ten gold bananas, two thumbs up and hurrah for Gorilla! What a wonderful book. It was a pleasure to read! If you just want to get comfortable and enjoy a book-this is the one I would suggest.

Output: Positive


Input: Consider Input: Hi-Tecs are the BEST, the coloring has come out of these, now kinda of a weird green color (?), but they have a good tight fit, did a week in them @ Isle Royale last summer ! No complaints.


Output: Positive
