Question

guillermo is holding still for 20 seconds in a position that looks like the top of a push up in order to work his core muscles. which exercise is he most likely performing? (1 point) ○ the bird dog ○ a bridge ○ crunches ○ a plank

Explanation:

To determine the exercise, we analyze each option:

• "The bird dog" involves alternating arm and leg movements, not holding a push - up - like position.
• "A bridge" has the body in an arched position (hips lifted), different from a push - up top position.
• "Crunches" are abdominal curls, not a static push - up - like hold.
• "A plank" (especially a high plank) is held in a position similar to the top of a push - up, targeting core muscles, and is often held for timed intervals like 20 seconds.

Answer:

D. a plank
