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.
Positive

By something else. This is the worst piece of machinery I have ever bought. Virtually impossible to cut any size tile on the diagonal. Typical imported junk!!!!!
Negative

This by far the worst movie that I have ever paid to see at a theatre. That is not to say that it wouldn't make a good rental; where through multiple viewers you could knock the viewing price down to 15 cents a person, but then that would still be too much to pay for this movie. WWE Entertainment should stick to what it does best - wrestling events where the story line is better inside the squared circle. Outside of a Terminator reference made to Robert Patrick, this is a total waste of 91 minutes of your life.
