Yeah, you really have to have great cardio too for such a sport. Weight training is equally important.
Diet is important to chess players

Don't forget the steroids. I seem to recall a GM that was a bit on the heavy side. And I'm rail thin and aren't half as good as I am trying to be. Maybe I should get fat...

I seriously thought Anand was going to die of old age during that match drew at 122 moves or whatever.
where do you get chess sets/tables like the one pictured above? or other interesting ones?

I'm sorry, but if you call chess (a great game) a "sport" like Kasparov does, then I would venture to guess you are highly unathletic and have never played a real sport.
I mean, does taking the bar exam for three solid days, or the medical boards, qualify as a sport? Just because they take super endurance and are grueling?

I read somewhere that in USSR, players of various games were tested for physical fitness. You know what? Chess players came on top!

Interesting. So they beat the players of checkers and Scrabble?
Did they theorize as to why? Perhaps lifting those heavy pieces? Or perhaps the mentality of someone who sticks to chess carrried over to training their bodies. That would be my guess. Then again, chess is considered a national "sport" and people are probably encouraged to make physical fitness a part of their training regimen. I'm sure it helps, as it would with any mental activity. There is a strong mind-body connection.
Compare their fitness against swimmers, soccer players, basketball players etc.
I know in any sport diet is very important. Just recently, research has found that obesity costs over 1 trillion dollars, almost as bad as war. How can you, as a chess player, play good chess if you are obese?
