Question

(01.01 lc)
which of the following is only a muscle - strengthening activity that can be completed in school? (3 points)

running
sit - ups
jumping
stretching

Explanation:

To determine the answer, we analyze each option:

• Running: Primarily an aerobic (cardiovascular) activity, not only muscle - strengthening and can be done outside school too.
• Sit - ups: Specifically target core muscles for strengthening. In a school setting, physical education classes often include sit - ups as a muscle - strengthening exercise, and it is less likely to be a primary activity outside school for general muscle - strengthening compared to the others in a non - school context.
• Jumping: Can be part of aerobic or plyometric (power - building) activities and is not solely muscle - strengthening, also done outside school.
• Stretching: Mainly for flexibility, not muscle - strengthening.

Answer:

B. Sit - ups
