The answer is letter
B.
A plateau period
refers to a point in time where there are no more improvements in certain
activities that a person is involved in. It could also refer to a lack of
enthusiasm and energy for doing things because they seem to be too normal. In
exercise performance, plateau periods usually occur when the training period
does not stimulate the performance of an individual and his/her overall goals.
The best answer for the question is letter B because this is an example of a
plateau period in an exercise activity. This person should try to engage in a
different training program to improve this skill all over again.
