Answer:
how long the athlete can sustain the activity
Step-by-step explanation:
"Endurance" tests your body's ability to carry on a specific activity for a particular period of time. This is often confused with "stamina," which tests the body's ability to do a specific activity without getting exhausted.
An example of an endurance training for the muscles is by doing 5 sets of body weight squats with repetitions, let's say 25. Depending on one's endurance, the repetition may be increased. Another example is by doing 5 sets of lunges with 15 repetitions on each leg (a total of 30 repetitions).
