Firstly, I have puny arms - those lens weigh a ton.

The child's puny arms and legs were stretched out convulsively, and the mother grew frantic at the sight.

There is scarcely any flesh on their puny arms, but their legs are as muscular as those of a greyhound.

They stretched out, forming the two horns of a horseshoe, like puny arms seeking to embrace the wide waters of Hudson's Bay.
