clamshells

Beach souvenir halves

Clamshells are the hinged two-part shells of clams and similar bivalve mollusks.

The shape lends itself to hinged containers that open and close the same way: food packaging, laptop computers, flip phones.

In exercise, clamshells are a movement where you lie on your side and open your bent knees like a clamshell: Do three sets of twenty clamshells on each side.
