Speaking to his team's official website Marsch explained how he has kept going for so long at the highest level.
"I think when I break my career up into segments, it's almost perfect for me to go D.C., then Chicago, and then Chivas," said Marsch. "In D.C., I was a rookie and I came in off the bench and I was learning what it was about to be a pro. Then came Chicago and I was on the field all the time but I was still learning and developing. Then I come here and I'm the leader and the guy that sets the tone every day. It's a good breakdown for me in terms of the stages of my career.
"I've paid more attention to my nutrition and how I take care of myself on a daily basis," said Marsch of his impressive longevity. "I'm in the weight room more and I do yoga more, and I think they make a difference for me. I'll credit Preki for some of that because he's played a long time and he knows what it's like once you get older. He's made me do yoga and made me go to the gym and I've grown to really like it.
"Right now, I still feel good about what I can do on the field, and how I can help out. I'm still motivated by the every day business of being a professional soccer player."
