When Garth'zel finally calls a halt to the 'lesson', Anakin is breathing hard, red faced, and sweat slicked, including his hair which has started to curl.

What he doesn't having technique or formal training he has in enthusiasm and stubbornness. And he doesn't really know how to pull his punches yet, meaning a few knuckles where busted and he is a little sore.

He doesn't mind, and he hadn't winced when the skin over his knuckles had split either.

Instead he waits for feedback.
