Newly acquired Cincinnati Bengals linebacker James Harrison claims that he estimates he spends at least $400,000 annually to make sure his body is ready for the grind of an NFL season. Harrison was officially introduced by the Bengals during a press conference held on Tuesday.

"My body is what helps me to make money. Whatever there is that I need to do to try and make myself better or get myself healthy, I'm going to do it," Harrison said. "It wouldn't be unreasonable to say that I spend anywhere between $400,000 to $600,000 on body work, as far as taking care of my body, year-in and year-out."

After he was released by the Pittsburgh Steelers, Harrison had to work out for the Bengals, who wanted to make sure he was beyond a knee injury that sidelined him during training camp and forced him to miss the first three games last season. He was in Arizona working out when the Bengals offered a two-year deal last month.

The former defensive player of the year says he uses a hyperbaric chamber in Arizona, and has his own staff of acupuncturists, massage therapists and homeopathic doctors. He'll bring them with him to Cincinnati, where he joined his new team for the first time this week.

"I'm still not able to do certain things, but as far as my physical health, I'm able to train a lot harder than I have been over the last two, three offseasons," Harrison said. "I'm able to do a lot more weight [lifting]. I'm able to just do a lot more things that my body physically couldn't do because of injury, or whatever it may be."

The 35-year-old linebacker is entering his 11th NFL season. He said it's essential for NFL players to spend money to maintain their health if they want to ensure longevity in the game.
