Final answer:
A spotter for the overhead press should be attentive and close to the lifter, ready to assist with the weight and prevent injury without interfering unless necessary.
Step-by-step explanation:
When spotting an overhead press, the spotter would need to stand close to the lifter to be ready to assist with the weight if necessary. They should keep their hands near the bar without touching it, ready to guide or help stabilize the weight, and prepare to help lift the bar back to the rack if the lifter is unable to complete the lift. The spotter must pay close attention to the lifter's form and provide the necessary support without interfering with the exercise unless it becomes evident that assistance is needed to prevent injury.
