Joyce Hansell

Here's a shocker: Joyce Hansell, the compulsive couponer set to appear on Monday night's episode of Extreme Couponing, admits she has a "very, very addictive personality."

Crazy Extreme Coupon-er compares high of couponing to smoking a crack pipe

But the real surprise isn't about her addiction to coupons. Hansell, who previously likened couponing to smoking crack, actually used to be a food addict. After a lifelong battle with her weight, Hansell decided to put down the junk food and pick up the clipping scissors. And she's dropped 100 pounds in the process.

In the exclusive clip below, Joyce leads her family in a peculiar "stockpile workout" which involves using canned goods and 12-packs of Canada Dry as hand weights.

Extreme Couponing airs Mondays at 10/9c on TLC.
