In 2011, Shinedown singer Brent Smith weighed about 222 pounds.  Brent's not a tall man.  He felt he was putting on too much weight and wanted to make a change.  So, he saw a late-night infomercial for the workout tape Insanity.

Because of the program, Brent has lost 70 pounds.  He went from 36 percent body fat to 12 percent body fat.  The change is obvious and he could not be more happy.  He's so happy that he is now actively promoting the workout.  He's also got the entire band involved.
