There is so much contained within a kata that it can seem overwhelming to start training it in a practical way. Something that I've found to be helpful is to choose just a few techniques and start live drilling with them. This is a video I put together showing how you can spar using the elbow, hook, and sweep found in Naihanchi.
Nice video Daniel! Always good to show how things should progress from drills to live application.
All the best,
Iain
