Right now, we are attending a 6(maybe 8, lol) week class on Sundays. If we can find time, we'll go to some runthrus, especially now before our trial. We do have some equipment in the yard, and we'll play with that for 10-20 minutes daily except after heavy agility days.
. If you know what I mean..... all in all - depends on your dog, but if you train daily it should be really only short sessions.
