Half And Half.
After he was done motivating himself, he took off towards the giant. The giant bellowed and swung its sword at him. The sword slashed horizontally in a wide arc in front of the giant. But it missed him because he dropped to his knees.
His momentum made him slide forward between the legs of the giant. He made sure to cut the leg of the giant behind the knee where there was a gap in the armor on his way through its legs.
This made the giant cry out in anger. That leg snapped and buckled. It fell to the ground and brought the giant together with it.
The giant waved his sword in a wide arc behind him to smash him to pieces. If he had been standing, then he would have been done in. But he had only one hand, so he couldn't stand easily like a normal person. He had to roll, which saved him.
The sword flew above his head. Meanwhile, he rolled to the left side of the giant. It was the side of the giant that wasn't in possession of a sword.
