How important do you think is physical fitness for your chess? Are you exercising (particularly for chess)?
@Schachmalanders I've been doing bodyweight-based strength training for a couple of years now, but for its own sake and not with chess in mind :D
There is probably some truth to 'mens sana in corpore sano' though. I could easily imagine it being the case that in the final stretches of a long classical game it might be easier for someone in good physical condition to stay fully concentrated and alert.
