For my belt Test I had to fight 6 6 minute rounds. I had to go from someone my belt to my Sensei at the end. Dude.....Sensei has those for real friggan' hits. My bells where ringing at the end. But fighting him is the best thing ever. I mean he's a hard opponent but I learn something every time I step in the ring with him.
It was awsome though, I was fighting him and he came around with a Spinning Back Kick and I saw him set it up and I managed to hit him with a spinning back fist at the same time. It was cool we both had to stop for like 10 seconds to recover
