Final answer:
A supinated grip, involving rotation of the forearm to have the palm facing upwards, is the correct answer for the described position of the palm facing the ceiling.
Step-by-step explanation:
The grip in which the palm is facing upwards toward the ceiling is known as a supinated grip. This term comes from the fact that supination of the forearm involves rotating the forearm so that the palm of the hand moves from the palm-backward position to the palm-forward position, ending with the palm facing up in an anatomical stance. In this supinated position, the radius and ulna, two bones of the forearm, lie parallel to one another. This contrasts with a pronated grip, where the palm faces downwards. A supinated grip is used in exercises such as bicep curls and chin-ups to target specific muscle groups effectively.
