Question

what does muscular endurance measure? *
force sustained over time
muscle size
muscle flexibility
maximum force in a single effort
what is the primary purpose of flexibility training? *
losing weight
increasing joint range of motion
increasing heart rate
building muscle mass

Explanation:

Muscular endurance is the ability of a muscle or group of muscles to sustain repeated contractions against a resistance for an extended period of time, so it measures force sustained over time. Flexibility training focuses on stretching to improve the range of motion around joints.

Answer:

1. Force sustained over time
2. Increasing joint range of motion
