Phelps tired and "absolutely destroyed" by weight trainning and the yardage

When asked if he was tired? Phelps responded: "I would say that's an understatement," Phelps said, laughing. "We've been getting absolutely destroyed, in the weight room and in the pool. Literally, I feel like a brick in the water." "..."

"I left just about everything I had in the pool for that race. I'm pretty happy with it. It could've been a little faster, but I'll take that for right now. And having those three races in 45 minutes was tough." The Detroit News: [Link]
