Over the winter, i seem to gain alot of weight. As a high school quarterback, that is not acceptable. Last summer, i think i went from 160 to 150. That's my gross weight loss. I'm not even talking about how much fat i lost. I gained a good amount of muscle over the summer, so i probably lost over 15 lbs of fat. I got my six pack back, and life was great. After the season, i just quit, and now my six pack is back in the fridge. I'll probably order some up next week and start again. These are great, and the results are amazing.

Ex Output:
Positive

As most people readers know, Jack Higgins has written many fine action-packed books. However, this book reads like a twelve-year-old wrote it. The characters are so transparent they could be ghosts.The author and his publishing house must really need the money to rip of the public in this manner. This is the last book I read by this author. One can only rest on his laurels for so long. I'm glad this book was handed down to me or I would have written a really nasty review.

Ex Output:
Negative
