"Biggest Loser" trainer Bob Harper stands up for farm animals

Although Jillian Michaels gets the most TV time, thanks to "Losing It With Jillian," Bob Harper certainly hasn't faded from the headlines since Season 9 of "The Biggest Loser" came to an end.

He was named one of PETA's Sexiest Vegetarians for 2010, and now, he is serving as the spokesperson for the annual Walk for Farm Animals.

The "Walk" is actually a series of walks in the U.S. and Canada, all benefiting Farm Sanctuary, an advocacy group that works to end cruelty to farm animals.

"I can't think of a better reason to get moving this fall than to raise vital funds and awareness for farm animals," Harper was quoted as saying in on PeoplePets.com. "When I think about the billions of sensitive, intelligent beings who are confined and mistreated on factory farms to produce foods linked with obesity, heart disease, cancer and stroke — that is all the motivation I need."

There are a few walks in Pennsylvania, including one in Philadelphia on Oct. 2. The event will feature vegan refreshments, which would make Bob proud.
