History: Bob grew up on a cattle farm, but moved to Los Angeles to become a fitness trainer. He's developed his own fitness philosophy which he calls 'Inside Out'. If you've ever seen Biggest Loser before, you'll have seen Bob and know what he's all about. He's been with Biggest Loser since season 1 and follows a vegan lifestyle.
Why he's still with Biggest Loser: You'd think after 11 seasons, Bob would have followed Jillian's decision to leave but with the new trainers and contestants he feels Biggest Loser is being kept fresh.
What he brings to Biggest Loser: Has a passion for what he does, and enjoys the ability to use Biggest Loser to get his message out to people.
Thoughts on some of the new contestants: Jennifer is 330 pounds and he initially thought she'd be the crazy one but she seems to be disciplined and motivated. Also he hears lots of singing going on, one guy really loves to sing. "If singing burned calories this guy would be the thinnest person in the house".
What to look forward to this season: This season will break a lot of myths about working out when older. Discipline and drive helps a person lose weight, not youth. Biggest Loser ranch is a place you DO NOT want to go to. There is a lot of demand on each contestant and that's just in one day. It'll all start again the following day.
