I thought this was interesting:

Sheffield, reporting a day ahead of position players, said he dropped out of winter workouts with his good friend Barry Bonds in November to focus on strength work with a personal trainer. He arrived in camp weighing 218 pounds, seven pounds less than he weighed at the end of last season and 12 pounds lighter than he reported to camp last spring. He said he cut back on his running and improved his eating habits.

(Bonds') workout got me 25 home runs," Sheffield said. I'm not doing that any more. I feel like I needed to change the scenery, get my own trainer, and do my own thing. I feel I came to camp in shape this time. I went back to what made me successful in the first place, just living good.

I don't know if (Bonds) was happy or not, but I had to do what I had to do."

Sheffield, 34, said he plans to continue playing until he's 40. That would give him enough time to hit another 160 home runs and reach 500.

That's why I'm training, so I can get to 500 home runs and win a couple more World Series," he said.
