They use the estate square downstairs sometimes. Jumping over the (plastic) bench is a popular exercise - alas, they're mostly not very good at it, hence the curve in the top bar of the bench, but this also means scratter-scratter-scratter-clunk-RESOUNDING-CLUNK-screams-and-shouting, repeat every 60s for 4 hours. My brain was mush at the end of hour one, I'll be honest.
