Step-by-step explanation:
Prior to testing, clients should abstain from strenuous exercise for a certain period of time. The duration of the abstention period may vary depending on the type of testing being conducted. For example, if the testing involves cardiovascular fitness, clients may need to abstain from strenuous exercise for 24-48 hours to allow their bodies to recover and avoid affecting the results. On the other hand, if the testing involves muscle strength or endurance, clients may need to abstain from strenuous exercise for 48-72 hours to ensure their muscles are fully rested.
