A Weight Lifter Does Multiple Sets of Bench Presses, as Many

A weight lifter does multiple sets of bench presses, as many repetitions per set as she can.If she cools her palms while resting between sets, she can increase the total number of lifts she can complete in her workout.The most likely explanation for this is that

A) cooled skin makes it easier to grip the weight bar.
B) touching the weight bar with cooler hands causes a release of endorphins.
C) extracting heat from the palms increases the capacity of arm muscles to do work.
D) cooler palms trick the brain into feeling like the weight of the bar has decreased.
E) reducing the amount of heat generated from lifting reduces the amount of ATP being used.
