An interesting kata-focused lesson. We had a tough warm up - lots of abs work - but the lesson itself Sensei took us through heian yondan and godan repeatedly, over and over. I like using kata as a teaching tool. It breaks things up nicely, but also puts the moves in context and it's great exercise. Very early on I remember Sensei teaching us heian nidan even though most of us were white belts. As he often says, you're going to have to learn them anyway so doing them now will do you no harm. None of us lowly types could master heian godan but after 20 minutes of repetition we were at least memorising it and able to perform a kind of bastardised imitation. Not bad and something to hone in future - rough clay to work with.
