Fun in training

Monday's iaido practice was certainly one of the better I've had lately, intense and focused. Not as good as last Monday's, but good all the same. Some of it was led by the sensei, but other parts were "do this kata, I'll come around if it's needed" and I definitely managed to focus quite well. I may have ironed out a few details too, that I've been having trouble with. Wednesday, however, something upset my stomach, and I had to stay in bed.
Tuesday and Thursday were given over to Kali Sikaran, of course, and oh my did I have fun. I was exhausted after Tuesday's practice, and found out that 10 oz gloves get really, really heavy after a few hours of hitting people and things, and acting as a punching bag, or blocking... etcetera. Lovely. Though my blood pressure did that odd thing that happens sometimes when as soon as I calm down, I feel close to fainting, and have to sit down for a while. Bloody annoying.
Thursday, oddly enough, we were only three at practice. This meant a lot of focus on details and techniques. Some kadena de maño, some knife fighting, mostly, and I had my one Valentine's Day greeting: me and Jen were practicing cutting eachother over the chest with mockup knives (before learning to block such a proper cut), and suddenly grinned. In Sweden, Valentine's is called something which is translated something like "All Hearts' Day/Day of All Hearts" - thus making cutting eachother's heart out quite funny indeed! Quite cheering, which gave us new energy and focus.

I feel a bit guilty that I haven't made use of the snow that's been lying thick outside, but I really haven't been feeling up to going outdoors for anything but "musts", which have been going to training, this week. My social phobia seems quite mild compared to before, those times I go out with such a definite goal in mind. I did make up for it a little by going to Open Practice (Security Fitness) for its two hours today. And it was great fun! Nastily (and therefore awesome) exhausting warmup and strengthening exercises, and then, variations on the same fighty theme with empty hands, knife and stick. The theory behind it was also explained, which is always beneficial, at least to me. It was all finished with an "all on one" circle - one person in the middle, the others around, making attacks that the center person meets with, well, anything, really. It is a very good exercise, helping one to not get a narrow focus, meet a variety of attacks and learn to take hits - we used soft padded sticks, for example, and so, a bop on the head when I didn't manage to block an overhead hit was a good lesson rather than annoying or painful. One learns to act on instinct instead of over-think, and, if having a weapon, using it. In Miyamoto Musashi's way of thinking, taking over the initiative from your attacker.

So as you can see, I've been having fun in practice lately. Sometimes it seems pure drudgery, and then one have to push through no matter what. And sometimes, one feels elated and happy and, well, one has fun! It has kind of been what's been keeping me alive lately.

And this aspect of training, fun... Do you have fun, training? Do you have any ways of making your training fun, do you ever do that, or, is it perhaps something you've never thought of?
I have of course spoken at length about the joy of running, the lovely feeling of cleansed mind after iaido and so on, but... sheer fun, that's a bit different. Joking too much must not be done, because that frazzles concentration and focus, but still - sometimes you need some smiles, some grins, some laughs, or at least something that just feels... well, fun, amusing. So what're your takes on that?
