How long are the classes you teach?

We have black belt workouts at the school I run every once in a while and they are very informative. On top of being able to do things you can not do in a normal class, it also allows an instructor to get everyone "back in line" on certain variances that inevitably happen in all but the smallest schools.

Back to the original question though...my classes run 75 minutes for kids, 90 for adults.

If I had to change the class structure it would be to go longer rather than shorter.

Although I'm not an instructor, I do teach if there is a problem with the head making it. The regular class is a one hour slot, and I always find this isn't long enough. I usually follow this kind of format:

warm up (10 minutes), stretch (5 minutes), drill (20 minutes), partner work (20 minutes), cool down (5 minutes). This is pretty much exactly an hour. So if we have a late start, there's problems. It also means I sometimes feel rushed. If I need to stop to explain the theory of something, we don't have time at the end to still get a good work out.

even just an extra 15 minutes overlap to extend the theory or work out would be enough. But, c'est la vie, as they say. I'm not the instructor so I can't change much yet!

My regular classes are a good solid 2 hours reasonably divided between kihon, kata and kumite. Occasionally we will stretch it to 3 hours if people are up to it. At least once every three months we run a 24 hour class (24 hours non-stop.). My shortest class, which is a high school class is 1 hour 50 minutes due to school schedules and have to let students get to their next class. But at times when I was lucky to be the last class scheduled for the day, we'd always run over a half-hour. Life is short, it's best spent training.
