Physical fitness is given a lot of attention by players at the very top of chess. Here is a quote from an article that talks a bit about it.<p>“Anand has been pretty active as well,” says the Bad Sodener Zeitung. “He bought a season ticket for the swimming pool in Bad Soden and swam about 1000 metres per day.
