PISD Foundations Of Personal Fitness CBE Practice Test

When exercising for muscular endurance, what is the minimum number of repetitions one should do in a set?

9 3 6 12

Correct Answer:

Explanation:

Muscular endurance means the ability to sustain repeated muscle contractions with lighter resistance, so you perform more repetitions per set. Very low reps—like three or six—primarily target strength or power, not endurance. Among the given options, nine is the smallest rep count that still aligns with endurance training within this context, making it the minimum you’d aim for in a set to develop endurance. You could progress by adding more reps or adjusting rest or load later, but nine reps is the baseline here.
