Telling your partner outright things like, "Stop holding back on that throw, I need practice taking the breakfall out of it" is good too.
There have been times when I have outright told training partners that they are not doing me any good by going easy on me. We women need to be able to handle being treated rough and be able to still be able to think and act under those circumstances. We can't learn how to handle that unless we train against it. Having a bunch of big strong guys to train against is really a gift. After all it's not often that a woman gets attacked by another woman in a way that is a real threat. But it is not at all unusual for a woman to be pushed around by a man.
