I knew that my legs were shaking too hard to stand up.

He tried to control it, but his legs were shaking.

I tried to smile at him, but my legs were shaking under me.

She realized her legs were shaking and sat on the floor.

My legs were shaking so hard, I could barely stand.

His legs were shaking and he was having trouble seeing.

Rising wasn't too much more trouble, though my legs shook a little.
