What is the recommended rep range for muscular endurance workouts?

• A. 20-80 reps
• B. 12-20 reps
• C. 5-10 reps
• D. 100-120 reps

Answer: (A)

Muscular endurance is about how many times a muscle can repeatedly contract or sustain a contraction over time with relatively light resistance. To train that capacity, you push the muscle through many repetitions in a set, using lighter loads and shorter to moderate rests, so the muscle learns to resist fatigue and maintain performance over longer efforts. That’s why a higher rep range is used for endurance work, spanning a broad range like 20 to 80 reps per set. This level of repetition trains the muscle to sustain effort and improves fatigue resistance. Using very low reps with heavier weights targets strength, not endurance, and extremely high numbers like 100–120 reps aren’t practical or typically used in standard programs. The middle range (around 12–20 reps) can contribute to hypertrophy and some endurance benefits, but for focused muscular endurance the higher end of the spectrum—20–80 reps per set—is the most appropriate.
