A more local case a year or two ago involved a coach who made their kids do bearclaws down the track that was blistering hot. The heat caused 3rd degree burns on multiple hands and that coach was also in trouble for 'reasonable' and also common sense!
For instance swearing can get you ten pushups in my band. That is reasonable, and that will be allowed unless you have a stricter district policy limiting this. I do also always offer an out of detention if preferred for the small occasion I get too much griping. 1:100 have chosen that over the years.
My biggest thing with people saying laps is it's a massive waste of time. Someone comes late to rehearsal and you have them waste more time running around the field? Or you do that after practice and it's wasting your own.
