I can still vividly remember being at training as a 13 year old - and the players finished skills training and returned to the rooms to do extra work (ie. some were doing sit ups, push ups, chin ups, medicine ball stuff) and we were able to just walk into the rooms and watch.

I remember seeing Jako sit down on the floor, as if he was about to do sit ups with others, and all he ended up doing was laying down on his side and speaking to someone who wasn't a player. Gee he was fat for a footballer. Meanwhile, Libba started doing chin ups, and seemed to just keep going for ages and ages. He was incredible - but just needed a boost to get up to the bar!
