SOPP387: When I've finished practicing, I was completely wet

This question was sent by Lukasz. He writes: Hi, I suggest You a new subject, with a pinch of salt. Organ playing as a fitness. Yesterday evening I spent more than 1 hour the with Bach trio sonatas. When I've finished, I was completely wet. Maybe You could make a list of pieces that not only builds the skills, but also takes care of the physical form of the organist? ;-) ​ At the beginning of the list of pieces that make me wet I'll put of course Bach trio sonatas. What You will add to this list? What Yours friends from all over the world will add to it? I am very curious to know what Yours experiences are in this matter?
