Verified step by step guidance

1. Understand the concept of muscular endurance: Muscular endurance refers to the ability of a muscle or group of muscles to sustain repeated contractions or maintain a contraction over an extended period of time. It is different from muscular strength, which focuses on maximum force in a single effort.
2. Analyze the options provided: Each activity listed in the problem targets different aspects of physical fitness. For example, lifting maximum weight for a single repetition focuses on muscular strength, while yoga emphasizes flexibility.
3. Identify the activity that aligns with muscular endurance: High-repetition, low-weight resistance exercises are designed to train muscles to perform repeated contractions over time, which directly improves muscular endurance.
4. Compare the other options: Short sprints primarily improve cardiovascular endurance and speed, not muscular endurance. Practicing yoga enhances flexibility and balance but does not specifically target muscular endurance.
5. Conclude that performing high-repetition, low-weight resistance exercises is the most effective activity for improving muscular endurance, as it matches the definition and physiological requirements of this fitness component.
