Final answer:
To develop muscle endurance for the wrists, exercises engaging the extensor muscles, such as wrist curls and reverse wrist curls using lightweight bells, can be performed for a high number of repetitions.
Step-by-step explanation:
An appropriate exercise to develop muscle endurance for the wrists involves movements that engage the wrist extensors, like the extensor carpi radialis brevis, which extends and abducts the hand at the wrist. These exercises could include repetitive wrist extension and flexion exercises with light resistance, for a higher number of repetitions. An example would be using a lightweight bell, and performing wrist curls and reverse wrist curls to engage both the flexors, such as the flexor carpi radialis, and the extensors of the wrists. Over time, this can help build endurance in these muscles, allowing for continuous contractions over an extended period without fatigue, as is beneficial in sports like arm wrestling.
