  • As a supinator, he often needs to adjust his wrist position during weightlifting.

Examples

  • If you see just your heel, the ball of your foot, and a thin line on the outside of your foot, you have a high arch, the least common foot type. This means you're likely an underpronator or supinator, which can result in too much shock traveling up your legs since your arch doesn't collapse enough to absorb it.

Morphology

supinator = supinate (transparent) = supinate + or

Regular agentive formation from the verb 'supinate' using the productive English suffix '-or', so the meaning 'one that supinates' is directly derived.

Etymology

Supinator comes from the Latin supinare, from supinus meaning 'on the back' or 'bent backwards'. So the supinator is the muscle that turns the forearm and makes the palm face up, like when you hold your hand to the sky.
