His own muscles were quivering with the fight that had not happened.

He had turned very pale, and his muscles were quivering.

I could do this, she thought as a little muscle quivered between her legs.

The muscles of his back quivered and seemed about to relax.

His muscles quivered with the effort to hold back the fury.

His great muscles quivered to the excitement of the moment.

For a moment he held it there, his muscles quivering with the strain.

After a few seconds the strain made his muscles quiver.

He did not rest either, though the muscles of his legs were quivering with exhaustion.

The muscles of her legs quivered so that she could scarcely stand.
