Hi everyone,

Is it correct to say: ‘Bend your arms!’, ‘Bend your knees!’, ‘Bend your legs!’/ ‘Fold your arms!’, ‘Fold your knees!’, ‘Fold your legs.’

Is this a correct sentence: ‘After the accident my ulna or elbow-joint was fractured. The doctors put in a plaster cast, but when they took it off, I couldn’t straighten my arm anymore.’

Is it also correct to say: 'Straightened arms/ legs/ elbows/ knees.

Thanks
Alexandro.

Fold your arms, bend your knees, bend your legs.
‘Straighten’ is okay with all of them.
