In the cast comic-con 写真 misha and jared and jensen look like they are in great shape,Do they work out with personal trainers all 日 and never touch a doughnut?How do they stay in such great shape?

Loool they sure are fit. From various 動画 I've watched, I've come up with the following:

-Jared runs in the morning, comes back and showers then goes to set (which is why they say he takes longer to get ready)
-Because Jared is massive, he eats an insane amount. He 発言しました in an interview, that he eats everything, kinda like Dean's character. And he really really loves candy.
-Jared 発言しました he starting working out a lot during the early seasons of SPN, which is why Sam grew out from his boyish season 1 look, along with the hair (sadly) probably to complement Sam's 全体, 全体的です change in personality and maturity from a boy to a man (also allowing him and Dean to become like equals) if あなた check back, he was way less buff in season 1 then later
-They both must work out, because abs like that are hard to fabricate ;) not sure about misha, we haven't seen him shirtless yet
-Jensen 発言しました he eats quite healthy, unlike Dean, so Jensen eats kinda like Sam (with the salads and such) and Jared eats like Dean (basically everything)
-I'm not sure about Misha, but I'm sure that J2 keep him in shape with all the pranks loool

misha isnt really buff. almost at the end of season 6. he took off his シャツ and あなた can see hands clawing through his belly.
